Product Description

BT-BFV A/LT Type Butterfly Valve
Common universal design of non-pin stem and soft sealing 
Competitive price and plenty in stock for fast delivery

A and LT butterfly valves are produced with the advanced technology introduced from U.S.A. 

Features
The Type A and LT butterfly valve are of advanced technology from USA. We are the first one to produce this type of valve for more than 20years history.
Actuators: hand lever, worm gear, pneumatic, electric, etc.
DN rang is 50-1000mm.
This valve can be installed to the pipe of oil, chemical industry, food, medicine, hydroelectric, shipping, water supply and drainage, metallurgy, energy source, etc. systems, applicable to the mediums of various corrosive gas, liquid, semi liquid, solid, etc.
The valve consists of body, stem, disc, seat and actuator.
The actuator makes stem and disc rotate to achieve on/off operation and control flow.
1. Small in size and light in weight. Easy installation and maintenance. It can be mounted wherever needed.
2. Simple and compact construction, quick 90 degree on-off operation.
3. Flow curve tending to straight line. Excellent regulation performance.
4. Long service life. Standing the test of thousands opening/closing operation.
5. Wide selection of materials, applicable for various mediums.
