White PVC relief valve with adjustable spring and PTFE seat

Hayward Flow Control

Hayward Flow Control RPV1075TPE1 Relief Valve 3/4 in PVC PTFE EPDM Adjustable 50 psi

SKU CH-G2QK-5MY87

Adjustable PVC relief valve with PTFE seat and EPDM seals, factory-set to 50 psi for industrial use

  • Adjustable 50 psi relief protects systems
  • PVC body with PTFE seat resists corrosion
  • Zinc-plated spring ensures consistent operation
  • ANSI 372 and ANSI 61 compliant design
  • 5 9/16 in height fits tight installations

Purpose & Audience

The Hayward Flow Control RPV1075TPE1 is an adjustable pressure relief valve built for industrial plumbing systems. It suits plant engineers and maintenance teams who need reliable over-pressure protection on process lines.

Material & Seal Benefits

The PVC body resists many corrosive fluids while the PTFE seat and EPDM seals provide broad chemical compatibility. These material choices reduce the risk of seat degradation and extend service intervals in aggressive media.

Standards & Pressure Limits

The valve carries ANSI 372 and ANSI 61 certifications and is factory set to 50 psi. It is not intended for applications that require a higher relief setting or for systems that fall outside the listed pressure and material ratings.

Highlights

  • Adjustable 50 psi relief protects systems
  • PVC body with PTFE seat resists corrosion
  • Zinc-plated spring ensures consistent operation
  • ANSI 372 and ANSI 61 compliant design
  • 5 9/16 in height fits tight installations

Questions about this item

Will the PTFE seat or EPDM seals need periodic replacement?

The PTFE seat and EPDM seals are built for industrial use; replacement timing depends on your fluid chemistry and pressure cycles rather than a fixed schedule.

What limits continuous operation at the 50 psi factory setting?

The zinc-plated spring and PVC body set the practical limit; sustained pressure at or above 50 psi will cause the valve to open and relieve flow.

Does the PVC body transmit noticeable heat or vibration when the valve cycles all day?

PVC does not conduct heat like metal, so the body stays near ambient temperature, and the ANSI 372 design minimises vibration during relief cycles.
