Through the characteristics of the pneumatic control valve have?

Through pneumatic control valve has a compact structure, light weight, action quick, filling body channels in an s-shaped streamlined, small pressure drop loss, large capacity of valve, precise flow characteristic, convenient tear open outfit. Widely used in the precise control of gas and liquid medium, such as process parameters such as pressure, flow rate, temperature and liquid level in a given value. Particularly applicable to allow small pressure difference before and after the valve leakage is the workplace. This series product standard, adjust cut type, bellows seal type, jacket type heat preservation, and other varieties. The nominal pressure level products are PN10, 16, 40, 64; Body diameter range 3/4 '~ 200. Used by - flow temperature 200 ℃ ~ 560 ℃ range class. Leakage level standard level IV or VI. Flow characteristic of linear or equal percentage. A variety of specifications to choose from. Features: the top guide single-seat pneumatic control valve, compact structure, less components, easy maintenance. Metal valve core for a variety of workplace, grade IV leakage standard, ZXPQ type soft grade VI leak sealing structure of valve core standards. Body according to the fluid mechanics principle designed to uniform the flow channel, low flow resistance increase 30 ℅ rated flow coefficient. Wide adjustable range, inherent adjustable ratio of 50. Actuator adopts more spring structure, highly reduce 30 ℅, 30 ℅ reduction in weight. ZXPV type bellows seal type pneumatic control valve, the valve stem of mobile form completely sealed, plugging fluid leakage. ZXPJ type pneumatic control valve with heat preservation jacket, used for fluid after cooling crystallization, cause jam the occasion.
