Spool Type with Area-Ratio Advantage, Slip-In Valve - PDMC05S30A-50

The proportional pressure reducing valve PDMC05S30A-50 is a direct-acting spool-type valve.

When there is no energy, the spring pushes the control spool towards the solenoid system. There is flow through the valve from port 2 (consumer) to the tank port 1. When the inlet pressure fluctuates it provides an almost constant outlet pressure - depending on the energization of the coil. When the control current increases, the coil exerts a force on the control spool. It then connects port 2 (consumer) with pump port 3. This compresses the reset spring of the control spool.

What's more, the pressure at port 2 acts against the solenoid force over a circular ring area. So, when we reach the pre-set value, the pressure plus spring force and solenoid force are in balance. Therefore, there is a restriction on the connection between pump and consumer ports. Any pressure at tank port 1 is additive to the pre-set control pressure. The design of the valves specifically answers for high dynamic performance and low-pressure drops.

Features:

• A compact design
• An excellent dynamic performance
• A low pressure drop due to CFD optimized flow path
• An excellent stability throughout the entire flow range
• External surfaces corrosion-proof
• The coil seals protect the solenoid system
• Hardened and ground internal valve components to ensure minimal wear and extended service life
• Also, it is adjustable throughout flow range
• An excellent small signal characteristics
