product description: 

1. The valve group is designed for use in thermal power plants, petrochemicals, and other large-diameter pipe systems that require high-reliability two-way metal seals for opening and closing.

2. The valve group consists of two laminated metal-sealed electric butterfly valves. Both valves are high-reliability one-way sealing butterfly valves, which adopt a combination of opposite sealing directions to achieve a highly reliable two-way metal seal.

3. The valve block is available in flanged and butt welded versions for user selection. The butt welding type is small in size, light in weight, saves installation space and reduces leakage points; the flange type is convenient for maintenance and disassembly.

4. The valve group adopts electric butterfly valve. The user's electronic control system realizes the synchronous opening and closing of the two butterfly valves of the valve group. The user should specify the performance requirements of the electric device in the contract.
