Drain valve interlocks

Interlock description

Tank Bottom, Flush Bottom, Inline Valves. Strahman drain valves are used on process vessels and reactors and are designed so that they cannot clog. They are ideal for use in liquid or with slurries, polymers, and high viscosity fluids, which may solidify at room temperature. The type of valve is: sample valve, type M-seal (metal to metal seat) jacketed, piston design and pipe mounted.

Strahman Drain Valves are available in Disc Type or Plunger Type:

The advantage of disc type valves is a short stroke for open/close operation. Air cylinder operation is usually selected.

Ram valves / piston valves guarantee full flow as the valve disc (ram) travels completely out of the flow path.
