United Conveyor Corporation Introduces 40DH Heated Knife Gate Valve

United Conveyor Corporation (UCC) recently launched the 40DH heated blade knife gate valve designed for on/off isolation service in pneumatic conveying systems. The 40DH heated knife gate valve is specifically designed for systems located downstream of dry scrubbers and dry sorbent injection (DSI) systems. The new 40DH version utilizes a heated blade technology to reduce build-up and hardening of high calcium ash and sorbents.

The 40DH heated knife gate valve is designed for an operating pressure of 40 psi and is available in sizes ranging 4in to 14in. Featuring a spring-loaded packing design, the 40DH heated knife gate valve maintains seal pressure during operation, preventing leakage and extending the life of the blade and packing.

“The UCC 40D knife gate valve is delivering reliable performance with over 5,000 installed units worldwide. We are now pleased to offer the 40DH heated knife gate valve design which incorporates the same proven technology with a first-to-market heated blade version,” adds Dan Charhut, vice president of technology, UCC. “Properly heating the blade reduces buildup and pluggage, allowing the valve to close tight even in the most severe high calcium and high moisture environments.”

The 40DH heated knife gate valve incorporates proven design features, such as:

  • Spring loaded packing
  • Rounded blade edges
  • Precision-machined blade guides
  • Crowned packing gland
  • Adjustable and replaceable blade wedge pins

The 40DH heated blade knife gate valve can be configured with a hardened ductile iron flow cone, wear liner or replaceable seat for easy and economical rebuilds. The 40DH heated knife gate valve can be shipped fully assembled with limit switches and pre-piped with a solenoid valve to reduce installation costs.
