Overflow Valves

for liquids, gas and vapors


System-medium controlled overflow valves are simple and compact regulating devices which enable the flow to be precisely controlled; they are easily installed and maintained and control the pressure upstream of the valve without additional control elements being required. At the valve plug the upstream pressure to be controlled is in equilibrium with the force exerted by the valve spring.
