DESCRIPTION AND OPERATION

1. Description

The Hydrant Coupler (coupler) (see Figure 1) provides on/off control of fuel flow in pressure fueling operations. The coupler inlet port attaches to the outlet adapter of the hydrant valve. The coupler outlet port couples to a fuel hose. The coupler provides a leakproof connection between the fuel supply hydrant and the fuel hose.

The coupler is recommended for use in bottom loading applications.

2. Operation

A. Uncoupled

When the coupler is not coupled to a mating fuel hose inlet adapter, its poppet valve is closed, so that there is no flow or leakage of fuel from the outlet port. The flow control handle that operates the poppet valve remains locked in the CLOSED position until the coupler is coupled to the mating fuel hose inlet adapter.

B. Coupling and Opening

When the coupler is coupled to the mating fuel hose inlet adapter, the nose seal of the coupler is compressed against the sealing surface of the inlet adapter to form a fluid-tight connection. When the coupler is fully engaged and locked to the bayonet flange of the inlet adapter, the flow control handle is unlocked. Rotation of the flow control handle to the OPEN position opens the poppet valve, providing a flow passage into the fuel hose. As the system is being fueled, fuel pressure acts on the floating nose seal of the coupler to increase the sealing force.

C. Closing and Uncoupling

Rotation of the flow control handle to the CLOSED position closes the poppet valve and the flow passage into the fuel hose. When the coupler is unlocked and disengaged from the bayonet flange of the inlet adapter, the flow control handle is locked in the CLOSED position.

D. Adapters

Suitable attachment adapters such as swivels and/or 90-degree elbows may be used to adapt the coupler to any fuel system.
