Ductile Iron Pressure Differential Bypass Balance Control Valve
Product introduction:
800X Series pressure differential bypass balance valve is also
known as a electric pressure differential bypass valve, it is a
kind of valve for air conditioning system use to balance the
pressure differential between supply and backwater, to ensure
pressure difference between water supply/return water, keep
differential pressure on the precise constant values. This valve
can improve the utilization rate of the system, minimize noise in
the system, and avoid large pressure difference to the damage of
equipment.
800X differential pressure bypass balance valve is superior one
than other balance valves, it does not need other execution
machinery, completely rely on the medium's own pressure difference
to achieve the system balance function, saving energy and
installation space

Product features:
1. The valve body adopts the whole passage, streamlined design,
small fluid resistance, large flow.
2. Dual sealing between valve body, bonnet, piston cylinder
connection by sealing gasket and the sealing ring sealing, ensure
no leakage.
3. The valve body, a piston cylinder, piston double orientation,
movement is stable and reliable.
4. The entire stainless steel piston cylinder, the whole cast
pistons, NBR sealing ring, a perfect combination of prolonging the
service life greatly.
5. The introduction of foreign advanced technology of removable
seats, artful structure, has the advantages of novel design,
convenient repair and replacement.
6. The band back bore in the piston cylinder, appropriate to
increase the damping piston movement, which tend to be more stable.
