Designed for use in emergency shut down systems,
Manual Shut-Off valves are available in two types.
The Two-Way (2/2) valve is designated as a Block &
Bleed valve. When the panel knob is pulled out, supply
pressure is dumped to atmosphere.
The Three-Way (3/2) valve is designated as a Charge &
Bleed valve. In the normal operating mode of this valve
the inlet port is connected to the outlet port and the ex-
haust port is blocked. When the panel knob is pulled
out, supply pressure to the outlet port is blocked and the
downstream pressure is dumped to atmosphere.
Any backpressure to the outlet port of either valve while
functioning in the normal mode, will cause the valve to
shift as if the panel knob were pulled out.
