This product is a proportional relief valve designed for low-pressure and high-pressure system safety by venting excess pressure. It features a durable stainless steel structure (SS316) with options for Viton or Neoprene ‘O’ rings to ensure reliable sealing. The valve comes in multiple instrumentation end connection sizes (ranging from 1/4″ to 1/2″ in OD or NPT configurations) and is color-coded by spring configuration to calibrate precise set pressure ranges up to 6000 psi.
