Pinch valve DV995

for the chemical industryfor water systemsvent

Advantage • High operating safety and long service life • Requires little maintenance • Simple union of the valve to the pipe by the proven bonding or welding process Applications • Construction of chemical facilities • Water treatment Use • For the aeration of industrial plants Function • The valve ball / float obstructs the vessel by the force of the spring. The fluid or gases can not purge. If liquid is now removed from the container, a depression occurs in the container. When the forces -depression and strength of the dock- The valve is neutralized and opened. The protective air / gas can enter the container. Indication • Conditioned by operation, only vertical mounting is possible • The container can not be filled without additional deaeration. • The opening pressure of the float or ball is approx. 0.05 bar. • This value depends greatly on the temperature, the system pressure, the fluid and the degree of general fouling (crystallization), etc. • Valves are not suitable for media that reduce the opening or closing of the ball / float due to deposition or adhesion.
