Key Specifications/Special Features:
- Ductile cast iron ggg50 body
- Coated with rubber EPDM
- New type double-canister exhaust valve
- New double-canisters exhaust valve
- Summary:
- The new double-canisters exhaust valve consists of a big canister and a small one
- When there is no water in the pipe, the canister in the body drops down to the full opening place
- When water coming in, the air in the body is released from the big canister, then water can be filled into the pine immediately
- When there is no air in the pipe, water comes into the valve cavity and causes the two canisters rise up to the closing place
- And the big canister stays closed so as to improve the capacity of transporting water and to economize energy
- Since air is often dissolved into water, when transporting water, the air is released from water continuously, however, when reaching the quantity, the small canister will drop down with a small amount of air released from air vents
- Otherwise the air accumulating on the top of the pipe will reduce the pipe systems capability of transporting water
- When there is negative pressure in the pipe, the big canister drops down and the discharge hole is open
- Then the valve takes in air in good time so that it can avoid affecting normal water supply due to the negative pressure on the pipe
- Unique design: the two canisters are made of non-toxic engineering plastics of high strength, with concise structure, light weight, reliable and stable exhausting
