Non-return valve has upstream and downstream directional bleedsThe valve has an upstream bleed (1) and a downstream bleed (2) with a size proportional to the desired flow rate. The two bleeds are able to turn on their respective vertical axes.GANDRE JEAN PHILIPPE...
The Wedgetorque provides positive seating from mechanical thrust, ensuring tight sealing of upstream and downstream seats. 自动弥补磨损和加工温度波动造成的变化。 Automatic compensation for wear and process temperature variations. 制造和库存的Wedgetorque操作机构具有几个系列的尺寸,能够满足全系列楔塞阀门的需要。
The steady flow downstream of a mechanical valve was measured and the results matched well with previously obtained 2D PIV results, such as those of Shipkowitz et al. (2002). Measurements upstream and downstream of a deformable ... D Troolin,D Amatya,E Longmire - Meeting of the Aps Divisio...
This pressure acts on the control bellows generating a force which is balanced by the compressed control spring.The internal forces generated as a result of both upstream and downstream pressures acting on the area of the valve head are minimized by use of a balancing bellow...

On large compressors with large diameter actuated suction anddischarge valves(or valves with high differentials across them upon opening), a smaller, automated equalizing valve is often installed. This valve equalizes upstream anddownstream pressurebefore opening the large diameter valve. This permits the...
At the end of the charging time, the upstream and downstream pressures of the leak test valve should be the same with the DP showing very low. On the contrary, if the DP is still high, then the charging failure condition is acted and the leak test could not be carried out further. (...
A valve includes a body having upstream and downstream ports to measure upstream and downstream pressures and configured on a common axis, and a ball arranged in the body to rotate re the common axis between open and closed positions to allow for fluid flow and no fluid flow. The ball has...
The growing potential of the oil & gas sector through growing projects and expansions will lead to the adoption of a greater number of industrial valves. Oil & gas is among the key end-user industries of industrial valves due to the adoption of valves in various applications in upstream, mids...
The plug, in combination with the valve seat, forms pressure drop zone upstream and downstream of the sealing surfaces which reduce the pressure and gas flow velocities past the sealing surfaces during the initial phases of the opening and the final phases of the closing of the valve ...
