Fisher™ N100-N100A-N110 Series Bypass Valves

N100/N100A/N110 valves handle propane, butane, or NH3. A tapped boss allows gauges. Internal orifices remove sensing lines.

N100, N100A, and N110 Series valves are designed for use with propane, butane, and anhydrous ammonia (NH3) at ambient temperatures. A 1/4-inch threaded NPT tapped and plugged boss on the inlet side of the body can be used to install a hydrostatic relief valve or a pressure gauge. They have internal sensing orifices so that no external sensing line is required. These valves are designed for bypass applications on 2 through 4-inch size pumps.
