double door check valve

Dual plate swing check valve (TH-CKV-DPS)

 Two valve plates are fixed on the valve body along a pivot; The two springs are installed on the butterfly plate above the sealing surface; Pushed by the medium flow pressure, the spring is compressed, forcing the butterfly plate to open; When the medium flows backwards, the spring forces the valve to close.

Easy maintenance, long lifetime; Simple & economical; Low cracking pressure; Low pressure drop; Quick and sensitive switching; Good sealing performance.

silent check valve (4)

Silent check valve (TH-CKV-SLT)

It can be installed vertically or horizontally, the valve flap is flexible to open and close, and it runs smoothly, with low closing noise, safety, and few faults; The valve flap is spring loaded, and its rapid closing can effectively reduce the water hammer pressure and the sealing performance is good.

11 ball-check-valve-2

Ball check valve (TH-CKV-BA)

Large flow rate, small flow resistance pressure loss; The sealing performance is very good, no noise when closing, which can reduce the water shock wave; Can be installed horizontally or vertically; It can be used for pump outlets of cold water, hot water, industrial and domestic sewage network to prevent backflow of media.

Globe valve (9)

Globe valve (TH-GBV) The globe valve is a tool that relies on the pressure of the valve stem to make the sealing surface of the valve flap closely fit the sealing surface of the valve seat to prevent the flow of media. It is a forced seal valve and is one of the most widely used valves.

13 gate-valve-5

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 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) 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.

16 U-type-flange-butterfly-vlave-body

Valve body (TH-VBD) Definition of valve body: The definition of “valve” is a device used to control the direction, pressure and flow of fluid in a fluid system. A valve is a device that allows the medium (liquid, gas, powder) in piping and equipment to flow or stop, and can control its flow rate.

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

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.

18 buttefly-valve-stem-shaft-parts-1

Valve stem shaft (TH-VST) The valve stem is an important part of the valve, which is used for transmission. It is connected to the actuator or the handle, and the valve core is directly moved or rotated below to achieve the valve switching or adjustment effect.

19 marine-valve-seat-rubber-sealing-valve-seat-parts-6

Valve seat sealing (TH-VSE) The valve seat is a detachable surface part in the valve, used to support the fully closed position of the valve plate, and constitutes a sealing pair. The general valve seat diameter is the maximum flow diameter of the valve. For example, the valve seat material of butterfly valve is very wide, all kinds of rubber, plastic, metal materials can be used as the seat material, for example: EPDM, NBR, NR, PTFE, PEEK, PFA, SS315, STELLITE and so on.

20 bonnets-for-butterfly-valve-1

Valve bonnet bushing bolts nuts (TH-VBN) Valve accessories refer to the parts or components to which the valve is assembled; or the parts or components to be re-installed after being damaged. Valve fittings can be divided into two types: standard fittings and optional fittings. Standard fittings refer to the auxiliary parts provided at random. Optional fittings refer to the parts that can enhance product functions and improve product performance in addition to the standard configuration.

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

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.
