Butterfly Valve

The 10 inch butterfly valve is double eccentric structure allows reduced friction with seal ring and extended service life.
The flanged butterfly valve is flexible operation, labor-saving, convenient, not affected by high and low ring pressure, reliable sealing performance.
The flange butterfly valve can changing the disc seal ring,O ring,disc,stem and the packing,this kind of valve suitable for different medium.
Easy to mount and dismantle convenient for servicing.

This welded ends butterfly valve design makes the valve an ideal hard seal butterfly valve for bubble sealing in high temperature, high pressure and fire protection applications.

Due to the welding structure, without flange,and no need counter flange,the valve welded to pipe directly by welding rod，so finally the valve can achieve leakage in the pipeline.

This valve has no flange, while saving costs and it is convenient and very beautiful for piping and thermal insulation.

Lug type ductile iron vition seat butterfly valve easy to install and operate, hot sale, widely application.
Lug type ductile iron vition seat butterfly valve small in size and light in weight, can be mounted wherever needed.

Acid resistant SS304 butterfly valve, triple offset, worm gear and wheel to operate, body seal is welded SS or cobalt-based alloy, disc seal is 316 multi-layer assembly, which can anti-resistant.
Acid resistant SS304 butterfly valve have long service life and can be used in petroleum, chemical, metallurgy, etc. corrisive condition.

Wafer tripple offset CF8M butterfly valve is wafer type valve, three-eccentric butterfly valve, metal seat butterfly valve,
Wafer tripple offset CF8M butterfly valve has good performance on anti-corrosion working medium.
Easy to intall, operate, and maintain.
Wafer tripple offset CF8M butterfly valve has long service time with high quality material.

long extension rod stem butterfly valve, wafer type butterfly valve, one line eccentric, can work under ground.
long extension rod stem butterfly valve with FBE coated thickness 250 µm, wich suitable the under ground condition.

1. Steel hydraulic actuator butterfly valve mainly composed of valve, hydraulic station, quick closing actuator, PLC intelligent electric control box and special stroke feedback device;
2. Precision-machined rack and pinion hydraulic actuator, compact structure, stable operation, safe and reliable;
3. PLC intelligent electric control system, with high degree of automation, can control the system remotely and locally;
4. Using international famous brand automation components, the product performance is superior and the quality is reliable;
5. The power source for the normal opening and closing of the valve is generally provided by the supporting hydraulic pump station, and can also be derived from the main turbine hydraulic station;
6. The system power supply is 380V, and the control power supply is AC220V, DC220V, DC110V and other power levels;
7. The valve adopts three-eccentric multi-layer metal hard-sealed butterfly valve, high temperature resistance, flexible opening and closing, easy, and reliable sealing.

Quick iInstall hand lever butterfly valve is the centerline butterfly valve, which means the shaft center of the valve stem, the center of the butterfly plate and the center of the body are in the same position. The structure is simple and the manufacturing is convenient. Common rubber-lined butterfly valves belong to this category.

Fire fighting signal butterfly valve 's gear worm -drive device chest is set up the microswitchs inside the body.
1. At the gearing chest has out inside the body to and the pass to two micrswitchs. Two switches move respectively at the valve standard-sized sheet with when cutting outm the pilot lamp power supply in the connection control room " valve leavel" "valve pas"' make accurately shows the valve switch state.
2. In the gearing chest body The signal is closed down by the export valve to the microswitchaction when thme butterfly board is by 0-40 seat, and another can be sebded out the valve and opening the signal to often closing the contact during 40-90° seat. Can adjust the cam that the pressure was touched the microswitch, and show the different seats of butterfly board place.
