The operation of the gate valve is to perform a clockwise closing (CTC) or clockwise opening (CTO) rotary movement of the valve stem. When the valve stem is operated, the gate moves up or down on the threaded part of the valve stem.

The ball valve is designed to contain a ball in the valve. The ball valve is a form of quarter-turn valve that uses a hollow, perforated and rotating ball (called a "floating ball") to control the flow through it. It is open when the hole of the

Cast iron gate valves are used in commercial and industrial applications. Its typical services include: hot and cold water, HVAC, steam, gas and other general utility services.

Types of butterfly valves: lug type butterfly valve, U-shaped flange butterfly valve, double flange butterfly valve, fluorine-lined PTFE butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve

For non-vertical stem type valves, if the valve is opened, the stem will not move upward. The stem is screwed into the dish. When the handwheel on the valve stem rotates, the disc moves up or down along the valve stem on the thread, while the valve stem r

Our gate valves are cheap, but durable and reliable. We believe that our deep research and development and rich production experience are important reasons why we are trustworthy.

We produce cast iron wafer butterfly valves, with hand lever or worm gear Operator. Our Butterfly Valves are widely used in drinking water system, sewage system, fire-fighting system. Butterfly Valves can produce from size DN40 to DN2400.

Ball valves are often used for steam, water, oil, gas, air, and corrosive fluids. They can handle slurries and dusty dry fluids. The ball valve is not used for abrasive and fibrous materials, because it will damage the surface of the valve seat and valve

Ball valves and plug valves are very similar in basic functions and applications. Both are control valves used to provide tight shutoff in different types of piping units. They also work on the same basic principle, that is, using a porous disk to start o

Simple structure, convenient operation, convenient installation, good sealing performance, long service life, high reliability, good interchangeability of parts, and cost saving.

The sealing ring adopts seatback type, mortise type or directly vulcanized on the valve body. The sealing surface of the valve seat flange adopts an O-ring to cooperate with the pipe flange cone, and the sealing effect is good. It is easy to disassemble a

The easy operation, maintenance and versatility of the ball valve make it widely used in industry. This high-quality ball valve will be an excellent choice for shut-off and control applications.

Gate valves are the most common type of valve in any processing plant. It is a linear motion valve used to start or stop fluid flow. In use, these valves are either in the fully open position or in the fully closed position. When the gate valve is fully o

When the handle wheel is turned clockwise, steam and steam move down through the fluid flow, and the gate is squeezed between the two valve seats, so that no fluid leakage occurs when the valve is completely closed.

Resilient seat gate valves are used for purification and pumping of sewage, fire fighting systems, irrigation, industrial pipelines, etc. It has minimal head loss, 100% water tightness and full bore.
