Emerson Fisher's N110 Series is intended for bypass service on the smaller pumps (5 to 40 GPM / 18.9 to 151 LPM) used on stationary tanks or delivery trucks. Suitable for LPG or Anhydrous Ammonia (NH₃) installations, the valve has an internal sensing orifice and does not require an external sensing line. A vent opening of the sensing orifice channel allows trapped vapor to escape, eliminating any vapor in the system when the pump is started.
The compact size of the N110 Series (less than 6.5 in. / 165 mm. overall) permits installation in limited space. A 1/4 in. FNPT tapped and plugged boss on the inlet side of the body can be used to install a hydrostatic relief valve or pressure gauge. The valve does not have to be removed from the line for servicing; all internal parts can be reached by unscrewing the union nut.
