High Pressure Relief Valves H-900HP Series

Product catalog summary

Overview
The H-900HP Series is a high-pressure relief valve designed for applications where pressure fluctuations can lead to process issues, system damage, or personal injury. It is constructed from SST 316 and can handle pressures up to 6000 psi. The valves are available in various sizes and connections, including LET-LOK® and pipe threads, and can comply with CE/PED standards.

Specifications

Material: SST 316 construction
Maximum Allowed Working Pressure (MAWT): 6000 psi
Set Pressure Range: 50 psig to 6000 psig (3.50 to 414 bar)
Sizes: 1/4", 1/2", 6mm, and 12mm
Spring Designators: Identified by color for different pressure ranges

Materials of Construction
The valve components include a cap plug, adjustment cap, spring, bonnet, O-rings, and body, primarily made from SST 316 and fluorocarbon FKM for seals.

Pressure Temperature Rating
The valves are rated for various temperatures and pressures, with a maximum set pressure of 6000 psig at temperatures ranging from -18°C to 93°C.

Cleaning & Packaging
Valves are cleaned according to Standard Cleaning and Packaging Procedure 8184, with options for Oxygen Clean & Lubricant-Free Cleaning under Procedure 8185.

Testing
Each valve undergoes proof and burst testing, with factory tests ensuring proper assembly and performance without detectable leakage.

Cracking Pressure Range
Valves are available with different spring designators, each corresponding to a specific pressure range, identified by color.

Operation
The valves open when system pressure reaches the set pressure and close when it drops below. Initial relief pressure may be higher if the valve has not been actuated for some time.

Ordering Information
Includes details on valve type, body material, seal material, and optional treatments. Users must ensure proper selection and installation to avoid damage or injury.

Flow Data
Graphs provide air and water flow data at 70°F for different body sizes, illustrating pressure drop and inlet pressure relationships.
