DESCRIPTION

The Model DSP-40, a 2-position 6-way selector valve, is designed to operate either as a double selector valve or a series parallel valve. This conversion is performed by changing spools and blocking two ports. The valve can be operated with pilot pressure, pressure and a spring offset or solenoid.

To avoid pressure surges, all ports are interconnected during spool movement. In either of the two positions, the spool seals one circuit completely off from the other in the selector mode and separates the high- and low-pressure in the series parallel mode.

The valves are made of high-tensile ductile iron and include a heat-treated spool lapped to fit the housing. This reduces internal leakage and provides maximum efficiency.

The valves are designed with large flow passages, amply sized for the rated flow, which reduces the pressure drop across the valve.
