AlP-series static balancing valve is static hydro-working valve, having good flow characteristics, enabling proper flow allotment,and making quantitative flow, therefore effectively dealing with the indoor temperature about unevenly heating and cooling problem existing in heat supply (air-conditioning) system. As the static balancing valve having equipped with indicator, open locking device, and small pressure valve for flow measuring, it is only installed proper specifications of static balancing valves in each branch and usersâ€™ pipeline entries. Upon locking after once-for-all adjustment with special instrument, the total amount of water in the system could be controlled within a proper range so as to overcome the improper phenomenon of â€œlarge flow but small
difference in temperatureâ€ The static balancing valve becomes an ideal product used in heating system with highest mediumÂ temperature up to 100 C.
The balancing valveâ€™ s working ways include hydraulic automatic control and manual control but without extra conditions.Â The working temperature is normal one, with EN 1.6MPa or 2.5MPa, and the circumstance shall be clean and good.
Application: lt is widely used in pipelines of central air conditioning system, water supply and drainage, fire protection, petroleum, and chemical and engineering,as well as industry and mining enterprises, etc., especially used in pump house of the central air-conditioning system
Y type straight structure, low flow resistance, enlarging flow capacity.
Equipped with Internal lift stem without leaving operation room in advance.
Digital display hand wheel makes operation easy, swift and reliable.
Multiple sealing structure applied to stem
Anti-cavitation shield added, affectively protect valve from cavitation impact, and reducing noise and vibration.
Hygienic and corrosion resistant, stem, limit rod, gland nut,and regulating screw are made of stainless steel or copper.
The whole valve complies with sanitary standard, applying to potable water piping, hygienic, safe and reliable. Locking set
provides after adjusted balancing valve with reliable and safe lock.

Â Type select about static hydraulic balancing valve
Â Practical formula:Q=Kvx 4W where
Â Qâ€”Flow rate(m3 /h)
Â Kvâ€”Valve flow coefficient(flow in m3 /h at 1 bar diff.press.)
Â P â€”Diff Press.(Bar)
Â i.e.Put static balancing valve installed in flow rate 50m3 /h Â piping
Q=50 m3 /hÂ Â Â APO.O5Bar
Â According to the formular Q=KvX4XF Â calculation.Kv-222,Look up the valveâ€™ s Kv in size of DN 125 from the Â following table to obtain kvs that is 293. Put the number in the formula to get a practical flow resistance when Â Â the valve is in full opening which is 0.O2gbar equaling to 0.29 m height of water column.
