Needle valve to use

Needle valve easy maintenance, simple ball valve, seals are generally activities,Instrument manifolds removal of the replacement is more convenient. When fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface. Wide range of applications, from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied. Because there are wiping Needle valve opening and closing process, so the media can be used with suspended solid particles.Instrument needle valve Grease should Needle valve metal materials, rubber parts, plastic parts and the working media are compatible. Working medium for the gas, can be used for example, JP 221 grease. Coated on the surface of the seal mounting groove of a thin layer of grease, coated with a thin layer of grease on the rubber seals, valve stem sealing surface and the friction surface coated with a thin layer of grease.
