Construction - Heat treated sleeves and rotor are ground to a high micro finish, and close tolerances enable GFP/Rodgers 4-way rotary shear type valves to hold a load for long periods with minimal pressure drop.  Sleeve-type seals are accurately lapped to the rotor.  In addition, balanced pressures within the valve insure proper sealing force between the sleeve and rotor for leak proof shut-off and excellent performance characteristics.

Positive Operation - The valve operates by means of a lever which moves in a 90° arc.  The center (neutral) position is determined by a ball detent, and stops on the valve cap limit the travel of the lever at each end.

Minimum Pressure Drop - Large internal porting with cylinder cross sections enables flow rate with minimal pressure drop.

Easy Maintenance - Valves are quickly disassembled if necessary for maintenance.  They may be serviced without disturbing piping.

Long Life - Wiping action of seals discourages dirt accumulation.

Operating Data - Fluid temperature range from -40° to +250°F.  Standard O-ring is Viton.  Three-position detent is provided.  Handle rotates 90°: 45° to each side of center detent.

Ports - All ports will withstand 10,000 P.S.I. pressure.  Valve body has been pressure tested to withstand pressures in excess of 15,000 P.S.I.
