13 gate-valve-5

Gate valve (TH-GTV)

Gate valve (TH-GTV) A gate valve is a gate plate of an opening and closing part. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact of the valve seat and the gate plate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. The gate has a rigid gate and an elastic gate. According to the different gate plates, the gate valve is divided into a rigid gate valve and an elastic gate valve.

14 ball-valve-6

Ball valve  (TH-BAV)

Ball valve (TH-BAV) Ball valve is a valve whose opening and closing parts (balls) are driven by a valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. It only needs to be operated with a rotation of 90 degrees and a small torque to close tightly. Ball valves are most suitable for switching and shut-off valves

Y type strainer filter valve (11)

Strainer Valve (TH-STV)

Strainer valve (TH-STV) The filter valve (STRAINER VALVE) is also called filter: a device that performs filter pretreatment. The filter valve is the filter equipment necessary for the use of hydraulic control valves and sophisticated mechanical products that are prone to clogging. It is an indispensable device of the pipeline series for transporting media. It is usually installed at the inlet end of equipment such as hydraulic control valves, pressure relief valves, pressure relief valves, and fixed water level valves.

17 center-line-butterfly-valve-plate-disc-parts-4

Valve Disc/Plate, Flap (TH-VDP)

butterfly valve disc is installed in the diameter direction of the pipeline. Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. In the cylindrical channel of the valve body of the butterfly valve, the disc-shaped butterfly plate rotates around the valve shaft to achieve opening and closing, and the rotation angle is between 0° and 90°. When it is rotated to 90°, the valve is fully open.

21 manual-actuator-lever-handwheel-worm-gear-box

Valve actuators /actuation (TH-VAT)

Valve actuators /actuation (TH-VAT) Valve actuators are devices used to open and close valves. The manually operated valve requires someone to be on site, using a direct or gearbox connected to the valve stem for adjustment. Power-operated actuators, using pneumatic, hydraulic or electric power, can remotely adjust valves, or quickly operate large valves. Power-actuated valve actuators may be the final element of an automatic control circuit that automatically adjusts certain flows, levels, or other processes.
