Daniel Series 700 Model 750 Pressure Reducing Control Valves are high-performance hydraulic control valves engineered to accurately regulate downstream pressure within ±2 psi (±13.8 kPa), regardless of changes in flow rate or upstream pressure — making them ideal for oil & gas pipeline pressure control, custody transfer metering protection, pump suction regulation and industrial process systems.
Designed around a balanced, single-seated pilot valve with large ports, these pressure reducing valves deliver smooth linear action, positive ANSI Class VI shut-off and minimal pressure drop across a wide operating range, safeguarding sensitive metering equipment and flow control assets.
The robust 45° high-capacity valve body and unit-built cartridge construction allow all internal parts to be serviced without removing the valve from the line, maximising uptime and reducing maintenance for terminal, refinery and process installations.
Typical applications include meter over-pressure protection, distribution system pressure control, pump suction pressure management (positive NPSH) and pipeline delivery to storage.
