Fisher does not have an electric control valve

Butterfly valve is used in industry, its characteristics can withstand high temperature, the applicable pressure range is also high, the valve nominal diameter is large, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of metal ring instead of rubber ring. The butterfly valve is a circular butterfly plate as the opening and closing part and rotates with the valve stem to open, close and adjust the fluid.

In the valve design or use experience, the lifting valve packing is mostly asbestos packing or graphite packing or PTFE V-type packing, but these packings are limited by the number of valve opening and closing, that is, with the increase of the number of valve opening and closing, the packing will wear out, and the gap will gradually increase, to a certain number of times.

The Fisher Fisher Models 627R and 627MR are equipped with a stroke stop—an internal pressure relief valve that works even if the disc or linkage fails. When the valve diaphragm is rising, the push rod touches the stroke stop on the lever retainer, and as the valve diaphragm continues to rise, the pressure relief valve is beaten.

The Fisher FISHER control valve reduces maintenance costs, minimizing the effects of metal corrosion damage due to water spray. Learn about flash evaporation in control valves Flickering occurs when a liquid flows through a control valve and evaporates and retains the vapor. Scintillation with choke flow and cavitation have ...

1. Selection of gate valves In general, gate valves should be preferred. In addition to steam, oil and other media, gate valves are also suitable for media containing granular solids and high viscosity, and are suitable for venting and low vacuum system valves. For media with solid particles, the gate valve body should be equipped with ...

Electric actuator, also known as valve electric device, it is a name in different industries, called valve electric device in the industrial pipeline valve industry, and called electric actuator in the instrument industry, but now there is no clear distinction in the industry.
