Emerson Process Management offers large filler valves with heavy-duty construction throughout for rapid filling of ASME tanks or trucks. Thick-walled bodies, formed seat retainers and generous wrenching flats minimize damage to internal parts.

Fisher N100, N100A and N110 Series valves are designed for use with propane, butane, and anhydrous ammonia (NH3) at ambient temperatures.

Fisher N120 Series backpressure valve is installed after the meter, and it holds backpressure on the meter until vapor is forced back to the tank through the vapor eliminator.

Fisher Type N201 automatic cylinder filling valve provides an accurate and economical means of filling cylinders. The assembly comes completely piped up and includes special parts that allow the slide weight on the scale to move to zero.

Fisher Types N480 and N481 hose end valves are intended as quick-acting primary shutoff valves for the end of the transfer hose on bobtail delivery trucks.
