Product Description
In some seriously application , such as medium full of sand and mud( eg in Huang River and sewage water treatment system ) , general valve can not run well and easily clog ,even will lead to the failure of the valve. Larger foreign material will make the disc stuck ,and result in lax sealing. Beside that ,big noise will appear because of large water hammer impact when the valve closed. Furthermore , some accidents will happened. Tube force control valve is developed to solve these problem
Product characteristic
Because of butterfly structure ,the valve has light weight and small volume ,and saves the construction cost . Without hydraulic control unit ,the cost is reduced and performance is increased . Due to less power is consumed ,it realizes energy-saving goal .
There are two types , diaphragm type and piston type ,widely use in all kinds of medium .To grantee the medium is clean before entering into diaphragm ,a filer have to be installed to remove the particles of the sewage . The filter have self washing function .Because a special unit is designed below the filter, slag discharging will be done periodically .
To meet the requirement of different operating conditions , control type is optional . Flow rate of the valve can be adjusted by manual or electric actuator .
Benefits
1,Easy to maintain
Less fault point without external power . The key parts of the valve is made by high quality material, without any maintain . The filter in external line has self washing function .
2,Beautiful appearance
Innovative structure , simple structure ,small volume ,and reliable running performance .
3,Maintenance easily
Due to driving by medium and connecting with pump aotomatically , the valve reduce the cost of operational people greatly .
4,Open the pump slowly
Only the inlet pressure up to the presetting value after opening the pump ,the valve can be opened . The current of starting pump is reduced to improve the security of motor and electric control system .
5,The valve opens quickly and closing slowly , which eliminating the water hammer and grantee the system safety .
6,The disc of valve is oblique butterfly type ,and water is flow horizontal ,so the loss of energy is less .
7,Tight sealing , nearly zero leakage
As metal-soft sealing or metal sealing structure is adopt , torque of friction will be greatly reduced; eccentric and oblique sealing pair, make the travel of closing valve becoming shorter , reduce the movement of distance sealing ring ,torque of friction become lower . So the valve can be opened in a moment . Further more , sand- proof function and pressure automatic compensation is also designed .

FAQ
Q: What is the cause of the leakage at the stem extension?
A: There are two reasons, one is the sealing ring damage; Second, the sealing ring wear, aging.
Q: How to solve the leakage at the stem extension?
A: The solution is to replace the sealing ring.
Q: What causes leakage at the valve and pipe connection?
A: First, the sealing surface is damaged or contaminated by dirt; Second, gasket failure; Third, the pipe flange pressure is uneven or not pressed.
Q: How to deal with leakage at the connection of valve and pipeline?
A: The following measures can be taken: repair the sealing surface or clean up the dirt; Replace the gasket; Press the flange bolt evenly.
Q: What is the cause of leakage in the valve?
A: There is mainly debris on the sealing surface, or the sealing surface is damaged.
Q: How to deal with internal leakage of valve?
A: Remove the debris on the sealing surface and repair or replace the sealing pair.
Q: What is the problem caused by the inflexibility of valve opening and closing?
A: First, the executive mechanism failure; Second, there are foreign objects blocked valve plate.
Q: How to solve the valve opening and closing is not flexible?
A: When the actuator fails, repair or replace the actuator; If foreign objects block, remove foreign objects, and be careful not to damage the sealing surface.
Q: Can the valve actuator adjust itself?
A: The valve actuator has been debutted before leaving the factory, and non-professional personnel are forbidden to adjust.
