ZMAS high pressure angle of high pressure regulating valve
ZMA/BS-220, 320 series of pneumatic thin transient angle business pressure regulating valve by the pneumatic adorable I play the implementation of institutions and angle off the pressure valve.
ZMAS high pressure angle pressure regulating valve adopts lens type valve structure, the valve seat is easy to replace, good sealing performance. The valve core is a plunger type, from the pressure difference asked core conditions for welding, tungsten cobalt alloy head, has the advantages of anti corrosion, erosion, greatly improving the service life of business.
Widely used in chemical industry, oil refining industry, especially suitable for the synthesis of nitrogen, urine is not the industry's pressure and differential pressure regulating business media.
