THROTTLE VALVE Series - VDRV7/VDV7 Veljan Throttle Valves VDV7 and Throttle Valves with integral Check Valves VDRV7 are for various applications requiring flow regulation without pressure compensation. In a circuit where the line pressure is almost steady and small function of oil flow due to pressure changes is permitted, the usage of this valve is ideally recommended. The integrated check valve allows reversed free flow from outlet port to inlet port. These va Ives are not intended for use as shut-off valves. For accurate control, pressure and temperature compensation is essential and for the same usage of Flow Control Valve Series V2F1 C is ideal. Contact VELJAN for further information.
