Parker Instrumentation Valves

Distributors for Parker and Honeywell

Parker offers the most comprehensive range of instrumentation valves in the Industry. These high quality valves perform in system pressures up to 150,000 psi. Innovative performance designs are available in all of our needle valves, ball valves, check valves, relief valves, metering valves, block and bleed valves, stream switching valves, and control valves. We offer these instrumentation valves in multiple configurations, end connection sizes and a variety of materials. Parker has the instrumentation valve to meet your system’s specific application.

NON RETURN CHECK VALVE (10,000 PSI) – HI CHECK SERIES

Parker’s Hi Check series high performance non-return valves are designed for unidirectional flow control of fluids and gases in process instrumentation applications. There is a choice of two check valve models, with cold working pressures of 10000 PSI (689 bar) and 6000 PSI (414 bar). Both check valves have an opening (or ‘cracking’) pressure of 10 PSI (0.7 bar). These robust check valves feature a two-piece metal seated body design to minimise any risk of leakage. The Parker check valves are available with a choice of integral male or female NPT, or single- or two-ferrule compression style ends, the compression ends enable users to eliminate the use of taper threads and thread sealant – further reducing the number of potential leakage paths and avoiding system contamination problems.
There is a comprehensive range of inlet and outlet connections, covering imperial sizes of 1/4″, 3/8” and 1/2″, and metric sizes of 6 mm, 10 mm and 12 mm. The check valves are designed to meet the pressure and temperature requirements of ANSI/ASME B.16.34, as limited by the seat materials. NACE compliant versions are available.

Features/Benefits:
• ANSI/ASME B.16.34
• Heat code traceable

RELIEF VALVES, 6,000 PSI – R SERIES

Parker R Series Relief Valves are unique since they offer both a low pressure valve line (RL4) and a higher pressure valve line (RH4). They are both designed such that when the upstream pressure exceeds the closing force exerted by the spring, the lower stem opens, permitting flow through the valve. Flow through the valve increases proportionately to the increase in upstream pressure. 

Features/Benefits:
• Pressure settings are externally adjustable while the valve is in operation. Multiple spring ranges provide greater system sensitivity and enhanced performance.
• Captured molded seat design is blow-out and chip resistant.
• Manual Override option with positive stem retraction is available for pressures up to 1500 psig (103 bar).
• This option permits the user to relieve upstream pressure while maintaining the predetermined cracking pressure.
• Color coded springs and labels indicate spring cracking range.
• Lock wire feature secures a given pressure setting
• Back pressure has minimum effect on cracking pressure.
