Ball valve, Gate valve, Globe valve from China
Ball valves are durable and usually work to achieve perfect shutoff even after years of disuse. They are therefore an excellent choice for shutoff applications (and are often preferred to globe valves and gate valves for this purpose). They do not offer the fine control that may be necessary in throttling applications but are sometimes used for this purpose.
The company has excellent mechanical processing equipment and modernized inspection&testing equipments more than 100 sets used for our main products: nominal size 1/2~42 (DN15 ~ DN1500), nominal pressure 150Lb~2500Lb (PN1. 0Mpa~PN42. 0Mpa), working temperature -101C~ +680 C, material include A105, WCB, 304, 304L, 316, 316L, 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti etc…on gate valve, globle valve, ball vlave, plug valve, check valve, butterfly valve, strainer and pumps products.
Ball Valves in sizes up to 2 inch generally come in single piece, two or three piece designs. One piece ball valves are almost always reduced bore, are relatively inexpensive and generally are throw-away. Two piece ball valves are generally slightly reduced (or standard) bore, they can be either throw-away or repairable. The 3 piece design allows for the center part of the valve containing the ball, stem & seats to be easily removed from the pipeline. This facilitates efficient cleaning of deposited sediments, replacement of seats and gland packings, polishing out of small scratches on the ball, all this without removing the pipes from the valve body. The design concept of a three piece valve is for it to be repairable.
Another type of ball valve we offer is the safety exhaust/energy lockout ball valve. This ball valve allows you to relieve potentially hazardous stored energy. The exhaust port of this ball valve automatically and continuously bleeds down compressed air trapped between the valve and the machine when the ball valve is closed. The venting action of this ball valve ensures that air-powered equipment is safe to service. This ball valve is rated for 200 psi operating pressure.
We are a professional manufactory specialized in ball valve series. The products range include: 1 pc ball valve, 2 pc ball valve, 3 pc ball valve, stainless steel ball valve, pneumatic ball valve, carbon steel ball valve, electric ball valve, ect.
Ball valves can be found in a number of different styles. Some of these include one-piece, two-piece, three-piece and lastly, what is referred to as flanged body construction. Each form of ball valve has its own good and bad points, all dependent on what each application calls for. Ball valves are made using an assortment of materials, some of which include brass, bronze, cast iron, copper ductile iron, metal alloys, stainless and other steel types, and plastics (including CPVC and PVC). Ball valves are to be found being used in a number of different industries. Some of these include the chemical, oil, pharmaceutical, allied process and also services such as corrosive and cryogenic.
