GEMINA fast acting spring loaded pressure relief valve


  • Fast acting relief designed to be used in transient pressure conditions
  • Flanged to discharge water away from the valve. (note discharge flange is larger than the inlet flange)
  • Sizes from DN80-DN150 inlet flange
  • Pressures PN16 and PN25

The CSA Mod. Gemina, with body and cover in ductile cast iron and internals in stainless steel, discharges the excess in pressure, with an immediate reaction, to protect the system against unwanted surges and water hammer effects. Its flanged outlet allows to direct the water outflow through a discharge pipe.
