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.
