MG(MK) Throttle And Throttle Check Valve

Throttle and throttle check valve types MG/MKValve types MG and Mk are throttle and throttle check valves in relation to fluid pressure and viscosity.Type MG (throttle valve)This valve throttles in bi-directions. Fluid flows through side hole (3) to the throttling orifice (4) formed between the valve body (2) and the adjustable sleeve (1). The cross-section of throttling orifice (4) may be steplessly varied by rotating the sleeve (1).Type MK (throttle check valve)In throttling direction, the spring (6) and the fluid presses the poppet (5) onto its seat, check valve is blocked. Fluid flows via the side hole (3) to the throttling orifice (4), formed between the valve body (2) and the adjustable sleeve (1).In the opposite direction, fluid pressure acts on the face of the poppet (5), check valve is opened and fluid flows freely. At the same time, part of the fluid flowing through the annular groove gets self-clearance as the desired effect.MG(MK).pdf
