Stainless steel gate valve is a simple and durable design, easy to use, but due to its geometry, it is sometimes difficult for users to enter. Gate valve is a flow control device that can gate and close the channels in the pipeline system. Its working principle is to block or open the channels through the valve body by rotating the handle, so as to realize the flow control. The gate valve has good sealing performance, strong bearing capacity and long service life

Forged steel Gate Valves are primarily used for stop valves fully opened or fully closed .They are not normally considered for throttling purposes,but more for slurries,viscous fluids,etc. Gate valves are characterized by a traveling wedge ,which is moved with the operation of the stem nut. Gate valves usually have a minimum pressure drop when fully open,provide tight shut-off when fully closed,and remain relatively free of contamination buildup.

The opening and closing parts of forged steel gate valves are gate plates. The movement direction of the gate is perpendicular to the direction of the fluid, and the forging gate valve can only be fully opened and closed, and can not be adjusted and throttled. The gate of the forging gate valve has two sealing surfaces. The two sealing surfaces of the most commonly used gate valves are wedge-shaped and wedge angles vary with valve parameters.

Stainless Steel Gate Valves are designed and manufactured to ensure leakage of less than 100 ppm (parts per million) of volatile organic compounds. Extensive base line laboratory testing (static and cycle testing) has been performed establishing critical design parameters necessary to achieve low emission sealing in the Med stem packing seal area and in the bonnet gasket sealing area, In-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the Med Stainless Steel Gate Valve meeting a maximum of 100 ppm VOC leakage prior to shipment.

carbon gate valve is one of the main valves used in oil and natural gas industry, pipeline engineering and other industrial water transportation facilities. The gate valve is an upper gate valve with two closed and open gate valve positions. The blocked flow door came into being. As early as when entering the filter, we indicated or added the use of special devices through the non sealing surface, our parts, rotating or rotating position, and found that the valve was opened or retreated to the closed or open position.

The opening and closing parts of Forged Steel Bellows Gate Valves are plug valves, the sealing faces are flat or conical, and the disc moves along the centerline of the fluid in a straight line. The motion form of the stem has the lifting rod type (the stem lift, the handwheel not lifting), also the lifting and rotating rod type (the handwheel and the stem rotates with the lift, the nut is located on the body). The corrugated valve is only suitable for full opening and full closing, and no adjustment and throttling are allowed. Valves of this type should be installed horizontally in pipes.

Product introduction: 

carbon gate valve is a comprehensive spring gate valve, which has a through hole and an outlet through hole. The inner holes are connected, and there is a channel that allows water to flow from the inlet to the outlet of the disc through a one-way channel; When it is lifted by hand, it closes the channel. Carbon steel gate valve is used for low to medium pressure control of liquid or gas gate. They are normally in open position and are designed to be maintenance free for a long time with minimum clearance between disc and seat.

Our steel gate is a valve made of high-quality carbon steel, which is used for heating and various heating systems for daily use. And gases, including HFCS and HCFCs. These safety valves also have an easy to read and easy to operate stem.

Carbon steel gate valves are the most common in pipeline applications and are used to regulate the flow of oil, gas or water. These valves usually consist of a gate leaf assembly and housing, which are straight through holes except for the setting of the diverter. The classic design consists of two or more sets of discs and or discs, which are sealed on one disc.

Forged Steel Gate Valves are suitable for using on various kinds of pipeline cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Molded flexible graphite is used for packing of Female Threaded Gate Valve. PTFE or combined packing material can be also used if being requested by the customer. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish (Ra 3.2μm). The stem surface, contacting with the packing, should be rolled and pressed after being precisely machined, so as to reach to the high finish and compactness (Ra 0.8μm) and ensure the reliable tightness of the stem area.

Pressure Seal Gate Valves is a valve realizing the closing and opening function by lifting the disc up&down as the closure member. The main advantages of API Stainless Steel Gate valve are smooth flowing passage, small flowing resistance and small operation torque, while the main disadvantages of this valve are: easy-damaged sealing face, long closing&opening time, large volume&weight. Gate valve is widely used on pipeline as it's suitable to be manufactured with big size. Gate valve is and generally for cutting off purpose but not intended to be used as a regulating valve because the sealing face would be corroded by the medium easily when valve is not in fully open or closed position.

The valve stem of the bellows valve adopts double sealing structure of bellows and packing to ensure the leakage and seal at the stem, especially for flammable, explosive, toxic and valuable medium. Bellows are made of stainless steel or Inconel material. The bellows seal structure is reasonable, fatigue resistant and long service life.

Cryogenic Gate valve refers to the valve with working temperature below -110Degree C and widely used in area of LNG, LPG and other cryogenic medium. There are two different types of bonnet designing. One is bolted bonnet, i.e. the body is connected with bonnet by bolts & nuts with spiral wound gasket(If required, metal ring gasket could be provided) between. And the other type is welded bonnet, i.e. the bonnet is welded to body directly. Cryogenic Gate valve is used to connect pipe and fitting or its accessories. Flanged connection has the features of easy installation, good connection strength and good excellent sealing performance. The flange connection consists of flanges, bolts, nuts and gasket. When we fasten the connecting bolts, it would press the sealing gasket between the flange which would have elastic deformation and fill all the small space between the two flanges' sealing face, thus to realize the good sealing.

The Slab gate valves is a sliding valve with closing parts as parallel gates. The shutter can be single gate or double gate with extension mechanism. The pressing force of the gate to the valve seat is controlled by the medium pressure of the floating gate or floating seat. If it is a double gate flat gate valve, the expansion mechanism between the two gates can supplement this compaction force.The flat gate valves can be divided into manual flat gate valves, pneumatic flat gate valves and electric flat gate valves according to the driving mode. It can be divided into flat gate valve with diversion hole, flat gate valve without diversion hole, flat gate valve of oil field, flat gate valve of pipeline and gas plate valve.
