Throttle and throttle check valve type MGMK for Rexroth

Product features

◉ Suitable for direct in-line mounting

◉ Pressure and viscosity dependent

Functional section

◉ Functional description: Valve types MG and Mk are pressure and viscosity dependent throttle and throttle check valves.

◉ Type MG (throttle valve): This valve throttles in both flow directions. Fluid flows through sided rillings to the throttling point. This is formed between the housing(2) and the adjustable sleeve (1). The throttle cross-section may be steplessly varied by rotating the adjustable sleeve (1).

◉ Type MK (throttle check valve): With flow passing through the valve in throttling direction, the spring and the fluid presses the poppet onto its seat, thus blocking the flow. Fluid flows via the side drillings to the throt-tling point , which is formed between the housing (2) and theadjustable sleeve (1).In the opposite direction, fluid pressure acts on the face of the poppet , thus lifting it from its seat and allowing fluid to flow freely, unthrottled, through the valve. At the same time, part of the fluid flowing through the annular clear-ance produces the desired self-cleaning effect.
