Ball Valve

Ball Valve

TANGCHENG is known as one of the leading ball valve manufacturers and suppliers in China. Here we bring you a wide selection of high quality and durable ball valve made in China. Ball valve, the opening and closing member (sphere) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-ball valve has a strong shear force between the V-shaped core and the metal seat of the hard-welded carbide alloy. It is especially suitable for medium with fiber-containing, micro-solid particles. The multi-way ball valve not only can flexibly control the confluence, sp

Trunnion Mounted Ball Valve

Trunnion Mounted Ball Valve

The Trunnion Mounted Ball Valve has a floating valve seat. After the medium pressure, the valve seat moves, so that the sealing ring is pressed against the ball to ensure the seal. Usually mounted on the upper and lower shafts of the ball, the operating torque is small, suitable for high pressure and large diameter valves. In order to reduce the operating torque of the ball valve and increase the reliability of the seal, oil seal ball valves have appeared in recent years, and the special lubricating oil is injected between the sealing faces to form an oil film, which enhances the sealing performance and reduces the operating torque. It is mor

Gate Valve

Gate Valve

The gate valve is a shutter of the opening and closing member. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal material to increase wear resistance, such as surfacing 1Cr13, STL6, stainless steel, and the like. The gate has a rigid gate and an elastic gate. According to the gate, the gate valve is divided into a rigid gate valve and a flexible gate valve. Advantages 1. The flow re

Check Valve

Check Valve

A check valve is a valve in which the opening and closing member is a circular valve flap and acts on its own weight and medium pressure to block the reverse flow of the medium. Check Valves The function of this type of valve is to allow only the medium to flow in one direction and to prevent flow in the opposite direction. Usually, the valve is automatically operated, and the valve flap is opened by the fluid pressure flowing in one direction; when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve flap of the valve disc act on the valve seat to cut off the flow. Check Valves The function of this t

Butterfly Valve

Butterfly Valve

The butterfly valve, also known as the flap valve, is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium means that the closing member (valve or disc) is a disc that rotates around the valve shaft to achieve opening and closing. The butterfly valve is a valve that uses a disc type opening and closing member to reciprocate about 90° to open, close or adjust the flow of the medium. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and fast
