IDENTIFICATION OF HAZARDS
NEVER adjust valves under pressure.
NEVER slacken or remove any valve parts under pressure.
NEVER use any mechanical aids i.e. wrenches, extensions to operate handles.
NEVER carry ball valves by the handle.
NEVER obscure valve body marking.
NEVER remove end connectors.
INSTALLATION
Wear suitable PPE before installation and follow appropriate site safety procedures.
Before installation, ensure that all valves are in the closed position.
H Series Manifolds & Needle Valves:
Needle valves supplied with weld connections will generally be supplied, unless specified and/or
agreed with customer, fully assembled. Prior to welding Parker recommend removing the Head
Assembly from the body to protect from heat. The valve body should be welded into the system
following the appropriate welding procedures. To prevent ingress of foreign contaminants into the
valve body, the Head Assembly hole and thread must be protected. After welding the Head Assembly
can be reassembled into the valve body:
1. Ensure the spindle is fully retracted by holding the valve head unit and turning handle (1)
counter clockwise until stop if felt.
2. Place stainless steel washer (8) into body recess at the top of the body thread. Apply suitable
lubricant to stainless steel thread (6) prior to assembling the valve head to the body.
3. Tighten bonnet hexagon (6) into valve body to 108Nm (6000 Psi / 414 Bar) Standard Head
Assembly *
122Nm (10,000 Psi / 689 Bar) High Pressure Head Assembly - Designated HP *
* Note - Monoflanges use Standard Head Assembly and Pro-Bloc use High Pressure Head
Assembly.
4. Place rolled locking pin into the nearest one of the 2 Ø3mm holes to the bonnet hexagon and
insert until fully located.
Hi-Pro Ball Valve:
Care should be taken to ensure that the end connector (1) is firmly held by an appropriate spanner /
wrench (size varies depending on size of valve) to prevent any movement when assembling or
disassembling pipe or tube connections.
Flanged Products:
Refer to the appropriate installation standard for the flange specification in question.

NPT: Use standard practice for NPT taper threads. Use an appropriate thread tape or sealant to
prevent galling.
A-lok/CPI: See separate instruction sheet supplied with A-lok products. For full instruction and best
practice on fabrication and installation of tube and A-lok/CPI tube fittings, scan the QR code below. *
When fitting A-lok/CPI, care should be taken to ensure that the end connector (1) (fig1) is firmly held
by an appropriate spanner / wrench (the size varies depending on the size of valve) to prevent any
movement when assembling or disassembling pipe or tube connections.
O-Lok: Take care to not damage the captive O-ring. For full instructions on O-lok assembly and
installation, please refer the O-lok section on page 55 of our Tube Assembly Guide which can be
found by scanning the QR link below. *
*For text versions of these QR codes, please See ‘Further Information’ at the end of this guide.
HANDLING AND STORAGE
Handling
Parker Products that utilise Needle and Ball Valves may be heavy. Ensure that local manual handling
requirements are followed.
Do not lift or carry by the operating handles, as this may cause damage.
Storage
There is no specified shelf-life.
Boxed products should be stored in a covered area, preferably indoors, and away from excessive
moisture, heat, or airborne contaminants.
The use of desiccant or corrosion inhibitors is not required during normal storage periods.

OPERATION
H Series Screwed Head/Bonnet:
To close: Rotate the handle (1) Clockwise until a positive stop is felt up to a maximum torque of 6Nm.
To open: Rotate the handle (1) Counter Clockwise until the backstop is located. The valve will be in its
fully open position after approximately 3 turns of the handle
H Series Outside Screw & Yoke Head:
To close: Rotate the handle (1) Clockwise until a positive stop is felt up to a maximum torque of 6Nm.
To open: Rotate the handle (1) Counter Clockwise until the backstop is located. The valve will be in its
fully open position after approximately 3 turns of the handle.

Hi-Pro Ball Valve:
To close: Operate the handle (17) until it is at 90° from the valve body centreline.
To open: Operate the handle (17) until it is in line with the centreline of the body and reaches the stop
pin.
Movement is limited to 90° by a mechanical stop pin.
Ball valves should always be fully open or fully closed. Do not leave in a mid-position.

MAINTENANCE
H Series Screwed Head/Bonnet:
CAUTION: Adjustment of the gland must be carried out at zero pressure
1. Fully close the valve by turning the handle (1) in a clockwise direction to stop lightly on seat
2. (max. 2 Nm).
3. Open the valve one full turn by rotating the handle (1) in a counter clockwise direction.
4. Loosen gland lock nut (4).
5. Tighten gland nut (3) to 11 Nm
6. Re-tighten gland lock nut (4) to 25 Nm.
