High pressure valve and fittings - Import export

The pressure relief valves GEMÜ N085 and N185 protect the plant and the piping system against gauge pressure and reduces pressure peaks. The third pipe spigot enables the valve to be installed in the main pipe. If the pressure increases, the spring is raised and the valve opens. The pressure is reduced to the preset value and can escape via the third pipe spigot into an adjacent pipe. If the pressure falls, the spring force presses the diaphragm in the direction of the seal seat and it is closed. The spring force can be adjusted as required using a set screw. - Valve adjustments can also be made under working pressure. - The optimization of piston, springs and control face ensures good control characteristics - The actuator is hermetically separated from the medium

This type is a pneumatically actuated valve with 2 port connections and 2 switching positions. The V2 has been developed for hot gases up to 400°C.

The lateral highpressure valves are valves with two or three connections and two switching positions. The pressure range extends from vacuum up to 500 bar. In this type of construction, the valve drive is not arranged coaxially, but laterally.

Coaxial highpressure valves are valves with two or three connections and two switching positions. The pneumatically operated valves of the VK series in particular have an extraordinarily positive relationship between high pressure range and high flow rate due to their high switching force.

Coaxial highpressure valves are valves with two connections and two switching positions. The pressure range extends from vacuum up to 400 bar. The wall thicknesses for the valve housing and head tube as well as the selection of the seals and the retaining screws are specially designed for high pressure applications. This series is typically used in gas filling stations and test benches, in compressor and hydraulic systems and in washing machines. The KB valve types have a special feature They do not require dynamic plastic seals and can be used in cryogenic application.

Within the family of pressureregulating valves, a technical distinction is made between series of bypass valves, inline valves and threeway valves.
