GENERAL SAFETY INSTRUCTIONS BEFORE INSTALLATION
FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF
THE PRODUCTS AND/OR SYSTEMS DESCRIBED HEREIN OR
RELATED ITEMS CAN CAUSE DEATH, PERSONAL INJURY
AND PROPERTY DAMAGE.
This document and other information from Parker Hannifin
Corporation, its subsidiaries and authorized distributors provide
product and/or system options for further investigation by users
having technical expertise. It is important that you analyze all
aspects of your application, including consequences of any failure,
and review the information concerning the product or system in the
current product catalog. Due to the variety of operating conditions
and applications for these products or systems, the user, through its
own analysis and testing, is solely responsible for making the final
selection of the products and systems and assuring that all
performance, safety and warning requirements of the application
are met.
The products described herein, including without limitation, product
features, specifications, designs, availability and pricing, are subject
to change by Parker Hannifin Corporation and its subsidiaries at
any time without notice.
Carefully read installation, operation and maintenance procedures
prior to installing or servicing valve.
Do not use valve as a safety shut-off valve when making repairs.
Do not install a valve before depressurizing system down to
atmospheric pressure.
Care must be taken to ensure that the valve materials selected are
suitable for the media being handled. Parker assumes no liability
for damage caused by improper material selection in the case of
corrosion from aggressive media.
CAUTION:Do not, at any time, make any alteration or modifications
to any angle seat valves without the express and written approval of
Parker’s Fluid Control Division.
DESCRIPTION
These valves are 2-way valves. The product line contains both
normally closed (N.C.) and normally open (N.O.) valves in stainless
steel construction. The valves can be actuated pneumatically. The
pilot operated models require a minimum operating pressure
differential to ensure valve operation.
Pilot valves may be ordered separately.
PRINCIPLES OF OPERATION
2-way PA Series - NORMALLY CLOSED VALVES
The angle seat valve is kept closed by a spring which presses
against a piston and piston rod forcing the seating seal tightly
against the valve seat. When pressure is applied to the actuator
pilot connection, the piston, piston rod and thus the seating seal are
raised opening the valve.
The valve tightly closes when pressure is removed from the pilot
connection.
The maximum permitted angle seat valve pressure and pilot valve
pressure and temperature ranges are described on the valve
nameplate.
2-way PA Series - NORMALLY OPEN VALVES
The angle seat valve is kept open by a spring which presses
upward on a piston and piston rod forcing the seating seal off the
valve seat. When pressure is applied to the actuator pilot
connection, the piston, piston rod and thus the seating seal are
driven down tightly closing the valve.
The valve opens when pressure is removed from the pilot
connection.
The maximum permitted angle seat valve pressure and pilot valve
pressure and temperature ranges are described on the valve
nameplate.
CAUTION: A minimum pilot operating pressure is required for
proper angle seat valve operation.

Installation Instructions
Mounting position and pressure limits: Valves can be mounted
directly on piping and are designed to operate in any position. The
valves may be installed in any line regardless of the direction in
which the line runs. However, for optimum life and performance the
valves should be mounted vertically upright so as to minimize wear
and reduce the possibility of foreign matter accumulating inside the
stem area.
Line pressure and pilot pressure must conform to Actuator
nameplate rating.
WARNING:Depressurize system and turn off electrical power to
the pilot valve before attempting to remove valve from piping.
Failure to depressurize the system could result in injury.
CAUTION: When the valve is to be removed from the piping
system, the pipeline must be drained completely before removing
the valve, especially with hazardous or aggressive media that can
be hazardous to health.
Installation Steps
Installation must be done according to all applicable Safety Codes
and Standards and by qualified personnel.
Inspect valve prior to installation. Damaged valves or actuators
must not be installed.
Ensure that the valves are installed whose pressure class, line
pressure, type of connection and connection dimensions
correspond to the usage conditions.
WARNING:Do not install a valve whose permitted pressure /
temperature ratings are inadequate to meet the operating
conditions.
Piping: Remove any protective enclosures from the body ports
and connect line pressure to the inlet port of the valve. An arrow on
the body indicates direction of flow. Use of Teflon tape, thread
compound or sealant is permissible, but should be used sparingly
on male pipe threads only. Connect outlet line to the opposite port.
Ports should not be subjected to excessive torque by use of an
oversized wrench, wrench extension or by impacting the wrench
handle. Do not use the valve to “stretch” or “align” the pipe. Using
the pipe to close a large gap can distort the valve or at least stress
it unduly, and possibly cause it to malfunction, or the threaded ports
may be damaged or stripped.
Actuation Connection
Actuator position can be adjusted with a clockwise rotation of the
actuator.
Connecting the actuator to the control:
A 3-way pilot is required to connect the control pressure for actuator
functionality.
For actuator types with springs, connect the pilot pressure to the
inlet of the pilot valve and the outlet of the pilot valve to the
threaded connection on the actuator head.
Pressure Testing and Valve Functioning
It is recommended that newly installed pipeline systems first be
flushed thoroughly to wash out all foreign matter.
The test pressure of an open valve must not exceed 1.5 times the
maximum rated pressure of the angle seat valve. The test pressure
of a closed valve must not exceed 1.1 times the maximum rated
pressure of the angle seat valve.
Normal Operation and Maintenance
The angle seat valves are operated by pneumatic control signals.
The valves do not require regular maintenance work.
During routine system checks, no leakage should be found in the
valve. If unacceptable leakage occurs, reference “Troubleshooting”
section for recommended solutions.
If a valve is to be removed from a pipeline carrying hazardous
media, the parts of the valve in contact with the hazardous media
must be properly cleaned and decontaminated before repairs are
performed.
CAUTION: When the valve is to be removed from the piping
system, the pipeline must be drained completely before removing
the valve, especially with hazardous or aggressive media that can
be hazardous to health.
NOTE: Depending on service conditions, fluid being used, filtration,
and lubrication, it may be required to periodically clean or replace
the valve.
For liquids, use versions with flow direction under the seat to avoid
water hammer effect
CAUTION:Do not expose plastic or elastomeric materials to any
type of commercial cleaning fluid. Parts should be cleaned with a
mild soap and water solution.

TROUBLESHOOTING
PROBLEM
PROCEDURE
Angle Seat Valve (NC, NO) fails
to operate.
1. Check that pilot air supply is properly connected.
2. Verify that pilot air supply meets the minimum pressure required to actuate the specific angle seat valve
model number.
Angle Seat Valve fails to close
(normally closed valve).
1. Check that the Angle Seat Valve opens and closes properly when pilot air is applied and removed from
the valve actuator.
2. Verify that there is no obstruction in the valve.
3. Verify that pilot valve is vented from valve actuator.
Angle Seat Valve fails to open
(normally open valve).
1. Check that the Angle Seat Valve opens and closes properly when pilot air is applied and removed from
the valve actuator.
2. Verify that there is no obstruction in the valve.
3. Verify that pilot valve is vented from valve actuator.
Internal Seating Seal Leakage
1. Check if the actuator has closed the valve 100 percent.
2. Verify that there is no obstruction in the valve that can prevent full closure.
3. Examine orifice in body for nicks. Damage may require a new replacement valve.
4. Inspect the seat sealing material for foreign matter or dirt accumulation. Worn sealing material requires
valve replacement.
