The H-1200 Series standard toggle valve is a compact design for normally closed
and quick on/off service. Moving the handle 90 degrees upwards opens the valve
to full flow and stops it firmly in the open position. Shifting the handle position
downwards shuts off the valve by spring return. The PTFE soft seat at the tip of
the stem provides a positive repetitive seal.

A three piece ball valve essentially separates the connection portions of the valve assembly from the body of the valve. These will be more expensive than either of the other two types, but their allowance for removing the valve body and trim from the piping system while leaving the connections in place may prove valuable for many applications. Full port and bidirectional shutoff can be provided by this construction.

When installed in a line between an upper zone and a lower area of heavy demand, the valve acts to maintain desired upstream pressure to prevent "robbing" of the upper zone. Water in excess of pressure setting is allowed to flow to an area of heavy demand, control is smooth, and pressure regulation is positive.
This fast opening, slow closing relief valve provides system protection against high pressure surges on pump start up and pump shut down by dissipating the excess pressure to a safe location and dissipating the excess pressure to a safe location.
