BKV BDV Model Valves are hydraulically operated control valves that reduce higher upstream pressure in the water network into a preset desired lower constant downstream pressure, and maintain it constant, regardless of fluctuating demand or varying upstream pressure. They are simple and reliable globe valves with full bore hydrodynamic body providing an unobstructed flow path and superior performance. When there is no flow in the system, it closes by itself automatically, and whenever the valve upstream pressure value decreases below adjusted downstream pressure value, it opens fully by itself. In cases, the valve downstream pressure value increases above adjusted downstream pressure value, it closes fully by itself.
BKV BTV Model Pressure Relief Control Valve are hydraulically operated control valves and designed to maintain valve upstream pressure value constant and stable, regardless of flow rate variations. When line pressure is higher than the adjusted pre-set valve pressure level, inlet pressure is kept stable by opening fully the valve. In case of sudden pressure increase, it releases the higher pressure wave in a pressure sensitive manner and in this way, the water system works regularly. When there is no flow in the main valve, it closes by itself as fully tightness. The valves hydrodynamic body is designed for unobstructed flow path and provides excellent and highly effective modulation capacity for high differential
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
