Above all,we suggest "Hard back Seat" as an economic choice if the valve size is less than DN500. We suggest "Soft back Seat" type when you have applications where valves need to be replaced on a regular basis and you don't have a machine to change the "Hard back Seat".…

The flanged three-way ball valve is a three-channel rotary ball valve. The valve core of the flanged three-way ball valve has L type and T type, which can meet different production process requirements. Either pipe can be used as inlet or outlet as required. The L-type valve cuts off two of the three pipes, and the T-type valve realizes the confluence and diversion of the three connected pipes.…

The third type is the pressure self-tightening bonnet forged steel globe valve. The valve designed according to this connection form, the valve body and the bonnet are connected by screw mosquitoes, and the internal pressure is sealed by the self-sealing ring. The advantage is that the greater the internal pressure, the more The better the sealing performance. You can choose the valve reasonably a…

Electric butterfly valve is a kind of electric valve and electric regulating valve. The main connection methods of electric butterfly valve are: flange type, wafer type and lug type. According to the transmission mode, it can be divided into manual, gear transmission, pneumatic, hydraulic and electric. It is an important execution unit in the field of industrial automation control. Electric butter…

The electric valve simply uses the electric actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the valve. The action force distance is larger than that of the electric valve, the switching speed of the electric gate valve can be adjusted, the structure is …

Electric gate valve consists of stem, valve body, bonnet, gate, drive and other parts (fasteners, stem nut, sealing packing). Rod (torsion shaft), gate valve is thus divided into two types: open rod gate valve and dark rod gate valve.…

Pilot-operated safety valve (also known as pulse-type safety valve) is a safety valve that relies on the discharge of medium from the pilot valve to drive or control the main valve. The pilot valve itself is a standard spring-loaded safety valve. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, whi…

The Y-type filter is a necessary filter equipment for the use of hydraulic control valves and precise mechanical products that are easy to block. It is an indispensable device for the pipeline series for conveying the medium. It is usually installed at the inlet end of the hydraulic control valve, pressure reducing valve, pressure relief valve, fixed water level valve and other equipment to elimin…
