We are offering pneumatic eccentric ball valve. name: pneumatic eccentric half ball valve classification: hemisphere valvemodel: bq641mnominal diameter:dn50600mmnominal pressure:pn1.04.0mpaapplicabletemperature425materialcarbon steel, stainless steel, high temperature steel etc. medium: water, steam, sewage, grain pulp, paper puli. brief introduction the executive system is pneumatic driven. A single cylinder or double cylinders are available according to the size of valve diameter. The advantages of semi-spherical valves have been fully developed to fulfill automation or semi-automation of valve operation. They are divided into 4 types: qbq641w, qbq641h, qbq641m, and qbq641m1, and have the following advantages: 1straight through. It is made for single direction sealing and an eccentric structure. The ball is divorced from the valve body when opening, therefore assuring a straight passage and making it impossible for the flow to be jammed. 2easy open and close. There is no contact between the valve core and the valve seat when opening, therefore causing little torque and free turning. While the function of squeezing and cutting between the semi-sphere and seat removes the fouling adhesives on the sealing surfaces when closing, therefore assuring a tight and reliable sealing. 3the eccentric structure of the sealing surface enables an automatic repairing of the spherical wearing. This results in a good sealing, long working life, and safety and reliability. 4the valve is a kind of hard sealing structure. Different anti-abrasive alloys are chosen for different medium. At the same time the hardness and anticorrosion are also guaranteed.

we are offering worm-gear floating ball valve. nameworm-gear floating ball valve classificationball valves model: q347f(h)nominal diameter: dn50600mmnominal pressure: pn1.010.0mpaapplicable temperature: 425material:carbon steel, stainless steelmedium: water, steam, oil, gassummarizeball valve was an important mechanical product which had a close relation with production, national defence and people living. it was applied to many systems. for example the exploitation, abstraction, procession and pipe transportation systems of petroleum, nature gas, coal and ore; chemical products, medicine and food production; electric power systems of water and electricity, firepower electricity and nuclear power; water supply and drainage system, heating and air supply systems of cities and industry corporation; farmland irrigation and drainage system; metallurgy system. it was pressurized in pipe systems to turn-off or turn-on the medium and transport it to the appoint place according to scheduled procedure.

We are offering low temperature ball valve. Namelow temperature ball valveclassificationball valves model: dq471xnominal diameter: dn50300 nominal pressure: pn1.610.0mpaapplicable temperature: -196150material:carbon steel, stainless steel, etc.Medium: water, steam, oil, acid, lye characteristic in order to prevent packing seal invalidation of stem in the low temperature condition, we adopt long-necked design in the low temperature valve. In order to avoid the cavity pressure rise, we install self-release pressure structure on seat to prevent medium temperature rising. Strictly controlling the materials chemical element and impact toughness in low temperature.
