Pressure relief valve - 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

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

Pressure relief devices for liquid-immersed transformers open in case of an internal fault and guarantee that the occured overpressure can properly release. Pressure relief devices close with decreasing pressure back to completely closed and leaktight position. Pressure relief devices for transformers can be installed in any position or inclination on the cover or the wall of a transformer. Upon request a transformer can be equipped with several pressure relief valves.

Dosing system DB 10: lubrication made easy The dosing system DB 10 uses a pressure vessel with a capacity of 10 litres. This is equipped with a filler ball valve and plastic funnel, a pressure regulator with bleed screw and a safety pressure relief valve. A float switch is fitted to regulate the fill level. There are two dosing valves on the underside. This dosing system is available in the following versions: DB 10 H – with poppet valve DB 40 – with 40 litre reservoir DB 40 H – with 40 litre reservoir and poppet valve

Mini solvent pump | reliable filling of small quantities The Mini solvent pump is a high-quality hand pump for small containers such as bottles, canisters and tanks up to about 10 litres. For reliable filling and dosing of solvents and readily flammable liquids. Simple principle - highly effective Mini solvent pump | reliable filling of small quantities The Mini solvent pump is a high-quality hand pump for small containers such as bottles, canisters and tanks up to about 10 litres. For reliable filling and dosing of solvents and readily flammable liquids. Simple principle - highly effective The hand pump works according to the excess pressure principle. An excess pressure is built up in the container with the pump ball, forcing the liquid outward. In this way only the hose, pumping tube and discharge come in contact with the liquid being filled. To ensure safety, a pressure relief valve protects the solvent pump against excessive pressure build-up, for example due to sunshine.

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.
