PROBLEM TO BE SOLVED: To facilitate the operation by a method wherein in off position, a valve rod contacts to rear vertex of a control hole, a handle is in a first position, and a cock mixing valve is in a maximum flow on position where the valve rod reaches the control hole ...
Enter a value of 1 for full-curve smoothing. The default value is 0.01. Cross-sectional area at ports A and B Area normal to the direction of flow at the valve inlets. This area is assumed the same for all the inlets. The default value is 0.01 m^2. Characteristic longitudinal length ...
The rotation angle of the ball valve is also detected by the drive, meaning that no other settings are required. The characteristic curve of the SUT drives can be set to linear or quadratic. In order to prevent the ball valve from blocking in the final position, the SUT drive makes a ...
The ball is of "V"pattern.At any position from full open to full close,it always keeps the standard geometry.The large adjustable extent is from 100:1 to 200:1,the CV curve of discharge characteristic is similar to the percentage curve,which may realize the precise control of the flow. ...
Besides reliability of the faucet, a mixing valve must possess other characteristics to be commercially acceptable. The maximum flow rate must be sufficiently great and the noise level of operation must be sufficiently low. Another characteristic is that the faucet must operate in an ergonomic friendl...
The pressure oil from hydraulic pump station flows to solenoid valve cabinet through high pressure oil pipe. The pressure oil flow is controlled through different oil pipe (OPEN, SHUT) according to different operation requirements, and the pressure oil pressure maintaining and monitoring are also ...
In this case, after hydriding, the pressure was reduced to 0.8 bar (equalizing to atmospheric pressure) and then the samples were quickly heated to 350 °C with the isolation valve closed. Once under isothermal conditions, the isolation valve was opened. Dehydriding reactions in such conditions ...
