●Mini type offers high flow in a compact and lightweight body, a wide
variety of style - available port O.D. sizes are 5/32~1/4", 3~6mm
● Ideal countermeasure to prevent condensation caused by
adiabatic expansion of small actuators which leads malfunction,
deterioration and the washing down grease of valves etc.
(Install quick exhaust valves close to cylinders or actuators.)
Some smaller models with 1/4" O.D. Available now. Other models
with Inch/NPT/10-32UNF thread are coming soon in Spring 2020.

■ How to adjust the speed (Exhaust needle type only)
1. Speed adjustment of actuators
①Increasing speed
Turn the needle in the counterclockwise from a
fully closed state. The more the needle is
opened, the faster the actuator moves. Make sure
to tighten the locknut at the desired speed.
The speed setting can be changed without
tightening the locknut.
②Reducing speed
Turn the needle in the clockwise when the
speed is too fast. Make sure to tighten the
locknut at the desired speed. The speed setting
can be changed without tightening the locknut.
■ How to replace silencer element
1. Replacement of silencer element
①Remove the silencer cover by loosening it in the
counterclockwise direction.
②Remove the silencer element.
③Attach a new silencer element to the metallic body
up to the end.
④Place the silencer cover over the element and
tighten the cover in the clockwise direction.
※Make sure to stop air supply before replacing
silencer element. No need to readjust the needle
after the replacement of silencer element.

■ How to insert and disconnect
1. How to insert and disconnect tubes
①Tube insertion
Insert a tube into Push-In Fitting up to the tube end. Lock-claws bite the
tube and fix it automatically, then the elastic sleeve seals around the
tube.
Refer to “2. Instructions for Tube Insertion”under “Common Safety
Instructions for Fittings” .
②Tube disconnection
The tube is disconnected bypushing release-ring torelease Lock-
claws.
Make sure to stop air supply before the tube disconnection.
2. How to tighten thread
①Tightening thread
Use a spanner to tighten a hexagonal-column or square part of the product.
Refer to “Table: Recommended tightening torque”under “2. Instructions for
Installing Controllers”in “Common Safety Instructions for Controllers”.

Detailed Safety Instructions
Before using PISCO products, be sure to read “Safety Instructions” and “Safety
Instruction Manual” and “Common Safety Instructions for Controllers”
Warning
1. When controlling the speed of actuators with needle type, slowly release the air by adjusting
the needle from a fully closed state. In case the needle is opened, actuator can move
suddenly. As for other than needle types, make sure to confirm the safety before operation.
2. Do not swing or rotate resin body of the products by force. It may damage to the
products and cause a fluid leakage.
Caution
1. The clogging of silencer element increases exhaust-resistance. There is a possibility that it
causes the system malfunction .
2. Make sure to provide a differential pressure when Quick Exhaust Valve is used as a
shuttle valve. It can cause a malfunction without the differential pressure.
3. When replacing a silencer element, make sure to place the silencer cover over the
element and tighten the cover by hand firmly. The element
for mini type, EQE can not be replaced .
4. Use a proper tool to tighten a hexagonal-column or square part of Quick Exhaust Valve. Refer
to “2. Instructions for Installing Controllers” in “Common Safety Instructions for Controllers”.
5. Adjust the tube direction while tightening thread within the tightening torque limits, since
some PISCO products do not swivel after the installation.
6. Exhaust air dirt may adhere to Exhaust port area (around outer hexagonal thread) of EQH (Exhaust
needle type) and become discolored depending on the use conditions and use frequency, but it is not
an abnormality.

2. Do not disassemble or modify PISCO products, which affect the
performance, function, and basic structure of the product.
3. Turn off the power supply, stop the air supply to PISCO products, and make sure
there is no residual air pressure in the pipes before maintenance and inspection.
4. Do not touch the release-ring of push-in fitting when there is a working pressure.
The lock may be released by the physical contact, and tube may fly out or slip out.
5. Frequent switchover of compressed air may generate heat, and there is a
risk of causing burn injury.
6. Avoid any load on PISCO products, such as a tensile strength, twisting
and bending. Otherwise, there is a risk of causing damage to the products.
7. As for applications where threads or tubes swing / rotate, use Rotary
Joints, High Rotary Joints or Multi-Circuit Rotary Block only. The other
PISCO products can be damaged in these applications.
8. Use only Die Temperature Control Fitting Series, Tube Fitting Stainless SUS316
Series, Tube Fitting Stainless SUS316 Compression Fitting Series or Tube Fitting
Brass Series under the condition of over 60℃ (140°F) water or thermal oil. Other
PISCO products can be damaged by heat and hydrolysis under the condition above.
9. As for the condition required to dissipate static electricity or provide an antistatic
performance, use EG series fitting and antistatic products only, and do not use other PISCO
products. There is a risk that static electricity can cause system defects or failures.
10. Use only Fittings with a characteristic of spatter-proof such as Anti-
spatter or Brass series in a place where flame and weld spatter is
produced. There is a risk of causing fire by sparks.
11. Turn off the power supply to PISCO products, and make sure there is
no residual air pressure in the pipes and equipment before maintenance.
Follow the instructions below in order to ensure safety.
① Make sure the safety of all systems related to PISCO products before maintenance.
② Restart of operation after maintenance shall be proceeded with care after
ensuring safety of the system by preventive measures against unexpected
movements of machines and devices where pneumatic equipment is used.
③ Keep enough space for maintenance when designing a circuit.
12. Take safety measures such as providing a protection cover if there is a
risk of causing damages or fires on machine / facilities by a fluid leakage.
PISCO products are designed and manufactured for use in general industrial
machines. Be sure to read and follow the instructions below.

Caution
1. Remove dusts or drain before piping. They may get into the peripheral
machine / facilities and cause malfunction.
2. When inserting an ultra-soft tube into push-in fitting, make sure to place
an Insert Ring into the tube edge. There is a risk of causing the escape of
tube and a fluid leakage without using an Insert Ring.
3. The product incorporating NBR as seal rubber material has a risk of
malfunction caused by ozone crack. Ozone exists in high concentrations
in static elimination air, clean-room, and near the high-voltage motors,
etc. As a countermeasure, material change from NBR to HNBR or FKM is
necessary. Consult with PISCO for more information.
4. Special option “Oil-free” products may cause a very small amount of a fluid
leakage. When a fluid medium is liquid or the products are required to be
used in harsh environments, contact us for further information.
5. In case of using non-PISCO brand tubes, make sure the tolerance of the
outer tube diameter is within the limits of Table 1.
●Table 1. Tube O.D. Tolerance
mm size Nylon tube Polyurethane tube inch size Nylon tube Polyurethane tube
ø1.8mm ─ ± 0.05mm ø1/8 ±0.1mm ±0.15mm
ø3mm ─ ±0.15mm ø5/32 ±0.1mm ±0.15mm
ø4mm ±0.1mm ±0.15mm ø3/16 ±0.1mm ±0.15mm
ø6mm ±0.1mm ±0.15mm ø1/4 ±0.1mm ±0.15mm

ø12mm ±0.1mm ±0.15mm ø1/2 ±0.1mm ±0.15mm
ø16mm ±0.1mm ±0.15mm ø5/8 ±0.1mm ±0.15mm
6. Instructions for Tube Insertion
① Make sure that the cut end surface of the tube is at right angle without
a scratch on the surface and deformations.
② When inserting a tube, the tube needs to be inserted fully into the push-
in fitting until the tubing edge touches the tube end of the fitting as
shown in the figure below. Otherwise, there is a risk of leakage.
Tube end
Sealing
Tube is not fully inserted up to tube end.
③ After inserting the tube, make sure it is inserted properly and not to be
disconnected by pulling it moderately.
※. When inserting tubes, Lock-claws may be hardly visible in the hole, observed
from the front face of the release-ring. But it does not mean the tube will
surely escape. Major causes of the tube escape are the followings;
①Shear drop of the lock-claws edge
②The problem of tube diameter (usually small)
Therefore, follow the above instructions from ① to ③, even lock-claws
is hardly visible.
Good Imcomplete

7. Instructions for Tube Disconnection
①
Make sure there is no air pressure inside of the tube, before disconnecting it.
② Push the release-ring of the push-in fitting evenly and deeply enough to
pull out the tube toward oneself. By insufficient pushing of the release-
ring, the tube may not be pulled out or damaged by scratch, and tube
shavings may remain inside of the fitting, which may cause the leakage
later.
8. Instructions for Installing a fitting
① When installing a fitting, use proper tools to tighten a hexagonal-column
or an inner hexagonal socket. When inserting a hex key into the inner
hexagonal socket of the fitting, be careful so that the tool does not
touch lock-claws. The deformation of lock-claws may result in a poor
performance of systems or an escape of the tube.
② Refer to Table 2 which shows the recommended tightening torque. Do
not exceed these limits to tighten a thread. Excessive tightening may
break the thread part or deform the gasket and cause a fluid leakage.
Tightening thread with tightening torque lower than these limits may
cause a loosened thread or a fluid leakage.
③ Adjust the tube direction while tightening thread within these limits,
since some PISCO products are not rotatable after the installation.
