Industrial Choke Valve
Industrial Choke Valve:
1. Brief Introduction:
The choke valve is the throttle stop emptying valve, the pipeline of closed circuit device purpose. It is widely used in petroleum, natural gas, coal, mining, oil refining, airports, chemical industry, oil and gas storage and transportation and so on.
There are two types, adjustable choke valve and positive choke valve. Adjustable choke valves adjust the flow by the needle and the seat,
Positive choke valves adjust the flow by beans on positive hole.
