THM – EBG – Electro proportional pressure relief valve Features: This valve is combined with a proportional electro-hydraulic pilot relief valve and a specially developed low-noise relief valve. Owing to special vent restrict or, this valve can make pressure control more precise and stable.

THM – EDG – Proportional Pressure Relief And Flow Valves Pilot Operated Features: This valve consists of a small DC solenoid and a direct-acting relief valve. It serves as a pilot valve for a low ow rate hydraulic system or a proportional electro-hydraulic control valve and controls the pressure in proportion to the input current. Note that this valve is used in conjuction with the applicable power amplier. Flow adjustment range: 60 ~120 L/min

THM – EFBG – Proportional Pressure Relief And Flow Valves Pilot Operated Features: Pressure and flow is proportional to the input signal of the proportional solenoids. This proportional valve adopts two electrical loops to control pressure and flow of hydraulic system respectively. The power losses is very low and overall efficiency high, hence reduced power consumption. Using very small pressure drop to track load pressure and control the pump pressure. This relief and flow control valve is energy saving type that provide flow and pressure as per programmed for actuator / drive. It is an high efficiency and energy-saving valve.
