Pressure testing method for ball valves The strength test of the pneumatic ball valve should be carried out in the semi-open state of the ball. (1) Floating ball valve tightness test: the valve is in a half-open state, one end is introduced into the test medium, and the other end is closed; Turn the ball several times, open the closed end inspection when the valve is closed ...

Fisher control valves are divided into electric control valves, pneumatic control valves and manual control valves, and the following mainly introduces pneumatic control valves and electric control valves. Fisher pneumatic control valve is based on compressed air as the power source, cylinder as the actuator, and with the help of electric/pneumatic valve positioner, converter, ...

To extend the life of a Fisher valve, most of us pay attention to installation and maintenance, but operation is also important. For valves, it is necessary to be able not only to install and maintain, but also to operate. Dongguang valve pointed out: valve installation, maintenance, operation, no one is missing...

In recent years, with the development of mechatronics, electric valves, an important mechanical product, have ushered in the world's leading market. Compared with traditional valves (manual valves, pneumatic valves), electric valves are more resource-saving, safe and reliable in operation. In today's increasingly loud call for environmental protection and safety, electric ...

Routine maintenance is a planned overhaul before a control valve fails, which can be understood as preventive maintenance and usually includes the following tasks. 1. Stress relief Pipelines can produce various stresses due to improper combination or installation, such as thermal stress caused by high-temperature media, uneven tightening force during installation, etc.

There are intelligent positioners and mechanical positioners for valve positioners, and today we are talking about the latter mechanical positioner, which is the same as the positioner shown in the picture Schematic diagram of valve positioner structure In the figure, the components of the mechanical pneumatic valve positioner are basically explained one by one, and the next thing is to look at it.

Fisher expands its portfolio of ubiquitous measurement sensing technologies to help manufacturers unlock the potential of the Industrial Internet of Things to improve factory performance. Due to the increasing demand for businesses to leverage asset health and performance analysis software, smart sensors can provide data with the information it needs to optimize decision-making.

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.

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.

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.
