Wellhead positive choke valve 4 1 / 16" x 5000psioil well api 6a positive choke valve overview of wellhead positive choke valve the choke valve, a main component of christmas tree, is design to control production rate of the oil well, with working pressure up to 20000psi. Choke valves can be classified as follows: adjustable chokevalves and positive choke valves. By rotating hand wheel to drive the stem, the adjustable choke valve is designed to adjust the effective area available for the flow to accomplish control of production rate. The positive choke valve is design to accomplish control of production rate by changing flow beans. features of the positive choke valve * the positive choke valve is conformed with api 6a specification* the positive choke valve is made of aisi 4130 forging* it is easy to operate and maintance* reliable quality of the choke valve main technical data of the wellhead choke valvesize2 1/16" to 7 1/16"working pressure2000 to 20000 psimaterial classaa to ffproduct specificationpsl 1- 3temperature classp.Umediumoil, gas, waterjc petroleum equipment factory is expertised in manufacture of wellhead valves and other api 6a wellhead equipments. the wellhead valves include gate valve, check valve, adjustable choke valve, positive choke valve, manual choke valve, plug valve, mud gate valve etc. wellhead positive choke valve 4 1 / 16" x 5000psioil well api 6a positive choke valve
Duplex gate valve As a valve stockist, we keep duplex, super duplex, alloy 20, monel alloy 400, hastelloy, inconel alloy 600 and incoloy alloy 800 valves in stock, and can also offer them on short manufactuing lead times.
Inconel 600 needle valves are used in the manufacture of turbine engines. They are also used for nuclear power plants and oil refineries. It is a type of valve that uses an annular disc instead of a stem and seat. It has been used for many years in the aerospace industry because it can resist high temperatures and corrosive environments.
