butterfly valve

1. Exhaust Gas Smoke Louver Ventilation Butterfly Valve is made of high quality material, which can be well resistant to corrosion, high temperature, oil and acid 2. The surface of Exhaust Gas Smoke Louver Ventilation Butterfly Valve is beautiful and flat, and the professional production process improves the stable performance of the product. It is solid, compact and has a long service life 3. We can customize various specifications according to customers' requirements, and we will provide you with solutions

There are no connecting rod, bolt and other components in its interior, so some component problems will not occur in the use process, so the failure rate is very low. It's very convenient to use. It is a reliable valve device. Because there is a large gap between the butterfly plate and the valve body of Stainless Steel Damper Control 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. Because of the wide selection of materials, this kind of ventilation butterfly valve also has the characteristics of high temperature resistance, there will be no friction when opening and closing, and the service life is extremely long.

This worm gear butterfly valve has short structure size, small size, light weight and light operation. The 24 inch butterfly valve adopts a triple eccentric structure, which has the function of closing and tightening when closed. The butterfly plate can bear pressure in both directions, with excellent sealing performance and zero leakage. After opening, the sealing surface is completely out of contact and protects the sealing surface from damage. The body valve seat structure is adopted, which reduces the direct contact of the valve seat with the medium, thereby reducing the degree of erosion of the valve seat and extending the service life of the valve seat.

The EPDM butterfly valve design is novel and reasonable, the structure is unique, the weight is light, and the opening and closing is rapid. The centre-pivoted butterfly valve have small operating torque, convenient operation, labor-saving and smart.It can be installed and maintained at any position. The sealing material is resistant to aging, corrosion, and has a long service life. The soft seated wafer butterfly valve seal can be replaced, and the sealing performance is reliable to achieve two-way sealing with zero leakage.

The double way sealing butterfly valve have float seat, there have O ring between float seat and valve body, it can be used for double side direction of the medium in pipeline. The bi-directional triple eccentric butterfly valve body seat ring is surfacing of stainless steel Cr13 or 2205,hard and wear resistant, long life service. When the medium is chemical, then the seal ring on the disc can choosed PTFE material, which is possible to used in corrosive medium,stable performance.

Semi-lug butterfly valve can be ether mounted between two pipes by ordinay hexagon head bolts or mounted on the pipe end (lugged-type).Easy to installation. 4 inch butterfly valve used EPDM/NBR rubber seat, which can ensure the tightness of the valve, o leakage. Semi lug type butterfly valve can equiped by lever handle,worm gear box, electric actuators, pneumatic actuators, hydraulic actuators accoring to customers's requirements. All the actuators can easy to exchange.

The DN250 wafer butterfly valve have small size and light weight. Easy instllation and mintenance. Itcan be mounted wherever nedded. The NBR seat butterfly valve siple and compact construction, small torque when open and close,quick go degrees on-off operation. This kind of butterfly valve is energy saving and flow curve tending to straight line. Excellent regulation performance and long service life. Standing the test of tens of thousands openingclosing operations.

This U shape butterfly valve is drive by worm gear, with flange connection, according to GB/T12238 standard. This valve consist of body, disc, stem, etc. The center line butterfly valve is operated by the hand wheel on the worm gear, drive the stem rotate 90° and further drive the disc rotate by 90° to open and close. 16 inch butterfly valve used U shape constructure, which is short face to face dimension, save installation space, as the same time,suitable normal working pressure as the long type butterfly valve.

The high performance butterfly valve is no need to add O-rings and metal parts to assist the sealing. The lip-type sealing structure can compensate for changes in temperature and pressure to the valve. There is almost no friction when sealing, ensuring smaller torque and better sealing. BS butterfly valve use of a single PTFE valve seat design has good elasticity and high reliability. The lip-type sealing structure can compensate for changes in temperature and pressure, with long service life, small maintenance, and two-way air-free sealing.
