The characteristics of pneumatic cut-off valve products

Pneumatic cut-off valve product features to cardiac cut-off valve USES more spring actuator and regulating mechanism with three state is linked together, the whole height is reduced by about 30%, the weight can reduce about 30%. Cardiac valve body according to the fluid mechanics principle designed to uniform the low flow resistance of fluid, rated flow system increased 30%. Filled trims sealing part has tight and soft seal two kinds, tight type for carbide surfacing, soft seal type for qualitative material, shut down into the sealed performance is good. Cardiac balanced trims, improve the allowable differential pressure cut-off valve. Cardiac bellows seal type of mobile stem form completely sealed, blocking off the possibility of leakage of medium. Cardiac piston actuator, operating strength, using differential pressure is big. Pneumatic cut-off valve connection flange standard: press BG4216 - cast iron flanges Press BG9113-84 cast iron flanges 88、JB/T79- Method 94 half seal face style: PN10, PN16 for convex; PN10, PN16 is concave and convex surface, the body is concave. Structure length: BG12221 - 98. Actuator air signal number: female M10 x 1. * the valve flange and flange face distance can be made according to standard specified by the user. Such as: ANS, IJIS, DIN standards, etc.
