Overview
The ITT G638-5360-GH30 back pressure regulator rebuild kit delivers precision pressure regulation for critical industrial and instrumentation applications. This regulator maintains a constant upstream pressure of gas, vapor or liquid, making it an essential component for systems requiring reliable backpressure control and pressure relief functionality.
Key Features
- Designed for accurate regulation under low flow conditions and widely used for protection of analysis instrumentation or as a relief valve in supply pressure lines
- Available in brass and aluminum combination or stainless steel construction, with standard Buna-N diaphragm assembly or Teflon/Buna-N/Teflon for corrosive services
- Handwheel adjustment mechanism for precise pressure setting control
- Compact design suitable for inline installation with ¼” NPT connections
- Rebuild kit format enables economical maintenance and system restoration
Technical Specifications
- Regulated pressure ranges: 0–3 psi, 5 psi, 15 psi, 25 psi, 35 psi, 50 psi, and 125 psi (0–21 kPa, 35 kPa, 103 kPa, 172 kPa, 241 kPa, 345 kPa, and 862 kPa)
- Maximum inlet pressure: 150 PSI (1034 kPa)
- Two ¼” N.P.T. port connections with inlet marked “IN”
- Series: GH30 Conoflow
- Diaphragm Material: Buna-N (standard) or Teflon/Buna-N/Teflon (stainless steel)
- Application: Gas, vapor, and liquid service
