Since the movement of the valve plate of the Pressure Relief Valve is wiping, most Pressure Relief Valve can be used for media with suspended solid particles. Depending on the strength of the seal, they can also be used for powdery and granular media.
The Pressure Relief Valve has a small structural length and overall height, fast opening and closing speed, small fluid resistance when fully opened, and sensitive flow control when opened to approximately 15° to 70°. , the structural principle of the Pressure Relief Valve is suitable for making large-diameter valves.
① Requires throttling, adjustment and control of flow;
②Mud media and media containing solid particles;
③Occasions where the valve structure is required to be short in length;
④Occasions requiring fast opening and closing speed;
⑤ When the pressure difference is small.
Pressure Relief Valve can be used when there are double-position adjustments, constricted channels, low noise, cavitation and vaporization, a small amount of leakage into the atmosphere, and abrasive media.
When throttling is adjusted under special working conditions or strict sealing is required, or when the Pressure Relief Valve is used under working conditions such as severe wear and low temperature (cryogenic), a specially designed triple-eccentric or double-eccentric valve with a metal sealing belt adjustment device must be used.
Universal Valve.
The Universal Valve is suitable for bidirectional opening, closing and adjustment of ventilation and dust removal pipelines, gas pipelines and waterways in metallurgy, light industry, electric power, petrochemical systems, etc.
Metal-on-metal Universal Valve is suitable for heating, steam supply, water supply, gas, oil, acid and alkali pipelines, etc., as a regulating and intercepting device.
In addition to being used as large-scale pressure swing adsorption gas separation control valves, metal-to-Universal Valve can also be widely used in petroleum, chemical industry, metallurgy, electric power, food, medicine, water supply and drainage, gas transportation and other fields.
