160-RF Rate of Flow Pilot

The 160-RF pilot is a spring and diaphragm operated pilot designed to sense a differential across an external orifice plate. It is a normally open pilot that also has a sensing port is in the spring casing, above the diaphragm and is available in stainless steel. The inner valve is held open by the spring and when the control pressure below the diaphragm exceeds the combined forces of the spring and the sensing pressure, the pilot valve closes. The 160-RF is the standard rate of flow control pilot on all 106 and 206 series valves.

160-RF Rate of Flow Pilot

• The normally open pilot shall be of bronze construction with a spring to adjust the pressure setting and as a result, flow rate.
• The pilot seat, stem, yoke and inner valve shall be of stainless steel 316 construction and the inner valve shall have EPDM resilient compound for seating. The EPDM compound must adhere safely to the inner valve and be ground flat and square to assure maximum performance.
• The pilot stem shall be guided by a Delrin bushing in the spring casing above the diaphragm and totally remove from the flow of water in the main pilot chamber. The pilot guide and stem location above the diaphragm shall eliminate debris build-up and sticking as well as minimize turbulence and false readings on the diaphragm.
• The pilot shall be self-cleaning and self-flushing by locating the outlet in the bottom of the pilot ninety degrees to the inlet.
• A sensing port shall be provided in the spring casing above the diaphragm.
• Maximum working temperature: 180° F / 82° C
• Maximum working pressure: 400 psi / 27.6 bar
