First, E type,which having the structure of cutting off and transverse
section in the downstream of side seat enlarged suddenly can clear
the cavitation erosion also apply to the occasion of flow control,
high pressure difference, large backpressure.
Second, S type,whose closing directive part has slotted sleeve
also apply to the occasion of flow control, high pressure difference,
large backpressure. Its adjustability is matched with the fluid
status and can provide a better effect.
Third, F type,which can shorten the spead pipe in the body outlet
also apply to adjusting and opening & closing occasion. When
opening the water head lose will be less and the resistance will
also be small when fully opening.
Fourth, LH or SZ type,which installed muti-hole ring network
in the internal body's piston directive part also apply to adjusting,
anticavitation, high pressure difference, small backpressure (impounding
reservoir's access point), etc. Its flow control adjustability
and operation working are better matched with so that to clear
cavitation.
Fifth, VAG piston valve
can be used as release valve and anti-exposion pipe valve when
using in the water. VAG piston valve's LH type and E type can
be used as liquid level or pressure regulating valve when reposition.
VAG piston valve's LH type and S type can be used as flow control
valve when deliverying water. While E type, LH type or SZ type
can be used as discharge valve or pipe valve.
VAG piston valve can be used as protection valve for pump opening
or allocation for special adjust outlet part when using in the
sewage and water treatment or used as flow contol valve in the
water treatment. E type piston valve can also be usd as air flow
control valve in the sewage treatment. In the water supply the
VAG piston valve can adopt different outlet part as pressure or
flow control valve according to the liquid working, such as pressure
balanced pipe network.
