butterfly valve

▶ Ductile iron with long neck for insulation. ▶ Slim disc of acid-resistant stainless steel with machined and polished edges reducing the friction between liner and disc. ▶ Loose liner of EPDM with integrated gasket faces and "saw profile" for optimum grip in body. ▶ Low operating torques allowing use of cost-effective actuators. ▶ Wide selection of materials, applicable for various medium. ▶ Industries include: HVAC, Food and Beverage, OEM, Chemical/Petrochemical, Pulp and Paper, Water Purification, and Power & Utilities.

▷Small in size ang light in weight. Easy installation and mintenance. It can be mounted wherever needed. ▷Simple and compact constrcution, quick 90° degrees on-off operation. ▷Miniminzed operating torque, energy saving. ▷Flow curve tending to straight line. Excellent regulation of performance. ▷Long srevice life. Standing the test of tens of thousands opening, closing operations. ▷Bubbles-tight sealing with no leakage under the pressure test.

There is no connecting rod, bolt and other components in the part, so there will be no component problems in the process of use, so the failure rate is very low. Because there is a large gap between the butterfly plate and the valve body of the ventilation butterfly valve, there is enough expansion space, so in the process of use, it can effectively prevent the thermal expansion and cold contraction caused by the temperature change, and the butterfly plate will not be stuck

The industrial high temperature butterfly valve is characterized by high temperature resistance, large nominal diameter, carbon steel valve body and metal ring instead of rubber ring. Large high temperature butterfly valve is made of steel plate welding, which is mainly used for flue gas duct and gas pipeline with high temperature medium.

1. The ventilation butterfly valve has reasonable design, unique structure, light weight and quick opening and closing. 2. ventilation butterfly valve operating torque is small, easy to operate, labor-saving and dexterous. 3. Suitable materials are used to meet the requirements of low, medium and high medium temperature and corrosive medium. 4. There is no connecting rod, bolt, etc. inside, ventilation butterfly valve works reliably, has long service life and is not affected by the flow direction of medium

Carbon steel flange motor butterfly valve with electric actuator, easy to open and close, double eccentric butterfly valve, soft seat, simple and compact structure, light weight. Carbon steel flange motor butterfly valve has a reliable seal performance as reasonable design.

The Electric Actuator Ventilated Butterfly Valve produced by our company has the advantages of simple and reasonable structure, small leakage, small friction torque, flexible operation, good blade rigidity, corrosion resistance and complete varieties. Electric Actuator Ventilated Butterfly Valveis used to adjust the air volume of air duct. The valve is divided into manual, electric and pneumatic operation ways

1. It can be customized according to the requirements of customers. Different materials and different operation modes can be produced 2. Complete and scientific quality management system, control the quality of each procedure, and can issue quality test report

The structure of Pneumatic Ventilation Butterfly Valve is welded by using the center line disc and short structure steel disc, so there are no connecting rod, bolt and other components in its internal part, so there will be no component problems in the use process, so the failure rate is very low. It's very convenient to use. And because its sealing system adopts metal sealing, it has long service life and high temperature resistance. So it is widely used in building materials, electric power, metallurgy and other industries. Pneumatic Ventilation Butterfly Valve can also be customized according to the needs of customers.
