Introduction

These high performance check valves offer the user two options for cold working pressure ratings of Class 2500 and Class 4500, with an opening pressure of 10 psi max.
By offering a true two piece design, body leakage paths are kept to a minimum.
With the added opportunity to select integral compression ends the user can eliminate the use of taper threads and thread sealant. This avoids system contamination, reduces potential leakage paths, weight, space and,therefore, installation costs.

Introduction

The Parker High Pressure Relief Valve (HPRV) provides an automatic protection mechanism for process instrumentation systems. When upstream pressure exceeds the closing force exerted by the valve’s spring, the lower stem opens and permits flow through the valve’s outlet port - which can be ducted to a safe place or released to atmosphere. Flow rate increases proportionately to the increase in upstream pressure.
CE marked and certified to the highest Category-IV level of the Pressure Equipment Directive (PED), the HPRV valve’s design provides users with accurate and consistent cracking and resealing operation. The valve’s innovative seat design additionally operates over an extremely wide pressure range (150 to 6000 psi, 10.3 to 414 bar), providing a universal solution for the vast majority of instrumentation applications.
Pressure settings are externally adjustable. Eight different spring ranges provide greater system sensitivity and enhanced performance.
