Duplomatic Oleodinamica represents the real alternative in the hydraulics market. Duplomatic’s wide range of products and worldwide service network, grant its users a real competitive advantage.
The Duplomatic K4WA/C valve is a mechanically operated decelerating valve with BSPP threaded ports for in-line mounting on hydraulic lines. It is normally used to change the movement speed of the hydraulic axis, such as changing from fast to slow, or for slow stops. The valve is normally open in the free condition and allows free flow passage from port P to port A. The flow is partially or completely shut off byoperating the mechanical drive of the valve. It is always supplied with a built in check valve that allows reverse free flow from port A to port P.
