Double Throttle / Check Valves

We are highly reputed manufacturer and supplier of an unmatched range of Double Throttle / Check Valves in Bengaluru, Karnataka, India. Valve type Z2FS 10 is a double throttle/check valve in sandwich plate
design. It is used to limit the main or pilot flow of one or two actuators. Two symmetrically arranged throttle/check valves limit the flow in one direction and allow free-flow in the oppostie direction.
For meter-in control fluid passes from port A1 to port A2 via the
throttling point (1), which is made up to the valve seat (2) and the
throttling spool (3.1). The throttling spool (3.1) is axially adjustable via the spindle (4), thus allowing the throttling point (1) to be adjusted. At the same time the fluid in port A1 reaches spool side (6) via bore (5). The pressure present in addition to the spring force holds the throttle spool (3.1) in its throttling position. Flow flowing back from the service port B2 moves the throttle spool (3.2) against the spring (7) causing the valve to act as a check valve and allowing free-flow. Depending upon the way in which the valve is installed, the throttling effect can be arranged as a meter-in or meter-out control.
