Description Vendor

The Series SRH6 Spring Regulator is a high-pressure spring regulator designed for stable pressure delivery regardless of ambient temperature variations. It features a stainless steel body, a large red adjustment knob, and multiple ports for various applications. The SRH6 is configurable for different pressure reduction needs and includes a locked outlet option for easy in-field repairs. It is ideal for mission-critical pressure reduction applications, test systems, and high-pressure air systems in maritime and industrial settings. The regulator is optimized for performance and reliability, with a Cv value of 0.08 and an inlet pressure range of 420 barg (6000 psig) to an outlet pressure range of 0-250 barg (0-3625 psig). It is available with connections via 1/4 BSP or NPT ports and can be configured with optional materials such as HNBR, FKM/Viton, or EPDM for different temperature ranges. The SRH6 is a versatile and durable solution for high-pressure applications, ensuring consistent and reliable pressure control.

Use Cases

  • Mission Critical Pressure Reduction Applications
  • Test Systems including those requiring a fast response during start up and shut down
  • Connections via ½ BSP or ½ NPT Ports
  • HP Air Systems (Maritime, Industrial)
  • Typically used in hydrogen and related industrial applications

Capabilities

  • Stable in high-pressure drop / low flow applications
  • Fail Safe In-field repairs made easy with a range of hassle free spares and aftermarket offerings
