Type of the products: ZZYP type

Name of product: Relying on oneself type pressure regulating valve

Characteristic of the products: ZZYP type relying on oneself type pressure regulating valve needing and energy, it is the motive force source to utilize and is adjusted the one's own energy of medium, introduced to the executive body and controlled the valve core position, change pigeonholing difference and flow of both ends, make the pressure of the valve (after or the valve ) steady. Have sensitive movements, the sealing is good, the advantage such as being small that the pressure establishes and clicks fluctuating, apply gas , liquid , steam medium reduce pressure steady voltage or is it keep automatic control of steady voltage to let out extensively. This series of products have three kinds of structure of single seat (ZZYP ) , the collet (ZZYM ) , two-seater (ZZYN ): There are membrane types , piston type two kinds in the executive body: The function pattern reduces pressure and is regulated(B type) and lets out pressing with the valve with the pressure after the valve the pressure is regulated(K type). The grade of nominal pressure of the products is PN16, 40 , 64; Valve body requirements range DN20 valve is 300; The grade of letting out amount has three gear that II grade , IV grade and VI can; The flow characteristic, in order to drive quickly; The regulation that the pressure segments is from 1550MPa. But according to needing to make up and meeting user's operating mode demand.
