In the 19th century, due to the increasing use of gate valves in industrial operations, their intensive development moved forward rapidly. Over time, the materials involved in manufacturing have been improved and modified to suit different applications.

Good sealing performance improves the reliability of the system. The friction resistance is small, the opening and closing is forceful and flexible. It has a long service life and can be switched repeatedly. High pressure and high temperature resistance,

A stainless steel 3/4 ball valve is considered not only rugged and durable, but they also perform well after many cycles. In addition, the reliability of stainless steel mini ball valves is also worthy of attention, because they can be safely closed even

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

Because of its ability to cut off liquids, gate valves are often used in the petroleum industry. For extremely viscous fluids, special valves commonly called knife valves are used to cut off the liquid. A typical gate valve is designed to be fully open or

Gate valves are used in a variety of industrial applications, including oil and gas, pharmaceuticals, manufacturing, automobiles, and ships.

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.

Gate valves are widely used in all types of applications, suitable for above-ground and underground installations. Especially for underground installations, it is important to choose the correct type of valve to avoid high replacement costs.

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.

The three-piece ball valve uses the same dynamic multi-ring gland system as the needle valve to provide higher strength and integrity. When combined with the blowout prevention rear seat valve stem, it can ensure that it can withstand all operating proces

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

Push-in joints do not require solder, glue, unions or tools. Corrosion resistant to extend service life, designed for drinking water distribution and circulating heating applications.

The gate valve is the most common valve in the water supply system. It represents a linear motion isolation valve with the function of stopping or allowing flow. The gate valve is named after the closing element slides into the flow stream to provide clos

Its working principle is to lift or press a rectangular or circular gate connected by the valve stem to the fluid path by rotating the handle wheel clockwise and counterclockwise.

The gate valve can provide different discs or wedges. The range of the gate valve is usually determined by the type of wedge used.
