38650 vacuum breaker valve

Description of 38650 vacuum breaker valve

Structure of 38650 – Dn50

• System filling – During filling water into the pipeline, mass of air will be evacuate from kinetic air intake & exhaust hole. The floating ball moves upwards to close the orifice after water flows into the champer. With aerodynamic design and the anti-blow design, the floating ball ensure ontime shutting of outlet while the high speed airflow occurs.
• Pressurized Operation – The kinetic valves keeps closed under pressure from water.
• System draining – When the system or pipe is drained empty, negative pressure forms in the kinetic valve. Meanwhile the float move down to take in air against vacuum formation.
• The vacuum pressure relief valve operates similar to a one-way valve, allowing air to flow from the outside into the gas, water system with negative pressure appearing from the inside, but not allowing air or liquid to flow in the opposite direction from the inside out.

Application of 38650 vacuum breaker valve:

• The negative pressure anti-valve should be installed at the highest point of the system, in some cases it can be installed below where there is the highest risk of negative pressure occurring.
• Used to protect plants and equipment that cannot withstand vacuum pressure such as: heaters, saturated steam pipes, air pipes, cooking pots, presses, condensate tanks, misting systems, any equipment which way we don’t want vacuum pressure to exist.

Benefits and advantages of E38650 vacuum breaker valve:

• Advanced aerodynamic design;
• Big inlet size allowing massive air flow;
• One- piece floating ball design ensure ontime shutting of outlet while the high speed airflow occurs;
• Quality sealing – prevents leakage under low pressure conditions (0.1 bar/1.5 psi);
• PP material with corrosion, acid, alkaliane resistant features to be long lasting;
• Multi-installation size for various market demands;
