FIG780
FIG 780 is a through-going gate valve with a circular opening which allows
un-restricted flow path when the valve is open. Media which are in the flow path
while the valve is closing is moved inside valve body and as such will not hinder
the movement of the gate and valve closure. A shearing action between the circular
port opening in the gate and the seat rings in the body (both are suitably
hardfaced) allows closure even when some media particles obstruct the valve
closure. Secondary soft seating can be provided optionally to improve seat
tightness
The gate travels out of the valve body when the valve is closed and is protected by
a gate cover at the bottom. Flushing ports are provided in the valve body for
periodic cleaning of the body chamber.
Valves are offered in cast iron, ductile iron or stainless steel body construction with
stainless steel gate; other materials are available as specials. Manual, pneumatic or
electric actuation is available.
TYPICAL APPLICATIONS:
Difficult media such as: reject pulp, recycle pulp etc.
