Flanged concentric disc butterfly valve technical parameters
1. Equipmentusedin regulating or cutting off medium in pipeline.
2. Suitable for handies(DN50-300), Gear Operators, electric and pneumatic
control actuators
3. Standards of design and manufacture confoml to GB/T12238
4. Pressure test confoml to GB/T13927
5. Structure lengrth meet to GB/T12221
6. Side flange standard meet to GB/T17241.6.
7. For installation infomiation, please refer to "Operation manual of installation
and maintenance".
Note: Performance curve of fow volume means the relationship
between open degree of valve and flow volume. Norally butterfly
valve suitable to use in control fow. Whenvalve's open degree
under 30°, not recommend to use in flow volume control.
Flanged concentric disc butterfly valve ST026 D341X
- Driving device flange
Can be used in handles, gear operators, electric or pneumatic actuators.
- Bushing
Reduce driving torque.support stem, and effectively separate it with valve bodyreduce wear of stem.
- Surface of disc axle hole
Through treatmentofpolishing, precisely fit with seat.
- High precision disc external profile
Reach the requirement of bubble-tight, small start and stop torque, longerusage life ofseat.
- Stem seal
Stem is not easy to be distorted, eliminating possible leakage in stem.
- Strong precision key
Give possible attachment for manual lever or actuator.
- Precision taper pin
Ensure positive vibration proof. Stem to disc connection.
Easily feld replaceable.
- Integralstem design
High precision and reliability, convenient for start.
- Side seal
With no need of flange gasket.
- Body lined with rubberseat
Good integralsupport, stable and solid, stretch-proof, leakage-proof.
- 0-ring
Prevent leakagein axle end
Concentric Flanged Butterfly Valve Overall Dimension PN10 . Pn16
DN50 to DN1000 CV Valve-Flow Rate Coefficient
DN50 to DN1000 CV Valve-Flow Rate Coefficient
CV=when valve entirely opened,pressure difference in both sides of valve will be 1 pound/inch2 ,when fluid is 60°F clean water,flow volume of per gallon/min.flowing through valve .
CV=Q(G/△P) 1/2 Whereas: G=Specific gravity, clean water will be 1.0 Q=Max fow rate
△P=Pressure difference, lb/in2
C=The valve CV is the flow rate(m3/h) of pure water at normal temperature passing through the valve when the valve disc is fully opened and the pressure differential between the two ends of the valve is 10Kpa(1Kg/cm2 ) CV=1.17C
