DS05 DIAL SET PRESSURE REGULATING VALVE60DUST CAP(BLACK)LOCKING SCREWADJUSTINGKNOBDIAL RINGBONNETSPINDLESPRINGOPERATIONThe Honeywell Braukmann DS05 Dial Set PressureRegulating Valve is a balanced, direct acting pressureregulating valve. The DS05 provides constantdownstream pressure regardless of varying inletpressures and downstream flow demands.The spring force holds the valve in the open position untildownstream pressure, sensed by a port, is sufficient topress on the underside of the diaphragm and close thevalve. As downstream pressure drops due to demand,the force on the diaphragm is reduced and the valveopens. Adjustment is made by manually turning theadjustment knob clockwise to increase the thespring force and require a higher downstream pressureto close the valve. Similarly, reducing the spring forcelowers the outlet set pressure. A factory-calibrated dial isbuilt into the adjustment mechanism to allow outletpressure (no flow) to be set without a gauge. A lockscrew maintains the setting. A black plastic cover isprovided for additional protection.Once the outlet pressure is set, the DS05 automaticallyregulates to maintain the downstream pressure.
