Product Specification: |
|
| |
The 800X pressure difference balance valve is a kind of valve intended for use between the water supply part and the return water
part of an air conditioning system to balance the pressure difference.
The 900X emergency shut-off valve belongs to a kind of valve that is intended for use in a water supply system in which the fire fighting water and domestic water are connected in parallel and for the control of the direction of water supply. When a fire breaks out and a large
quantity of water is in great need for fire fighting purpose, the 900X emergency shut-off valve cuts off the domestic water supply
immediately so as to ensure enough fire fighting water. When the fire fighting is over and the pressure in terms of water use has dropped,
the valve switches on automatically to stay in the constantly open state and the normal domestic water supply is restored. This valve
makes it unnecessary to set a separate fire fighting water supply network in the system, thereby greatly reducing the construction cost
and water consumption. Furthermore, the valve is high in control sensitivity, safe, reliable, simple to debug and offers a long service life.
