KDV Dump Valve

The KENCO KDV Series “No-Freeze” Dump Valve is a pneumatically controlled valve designed for fluid level control in gas scrubbers, separators and other process pressure vessels. Model KDV Dump Valves are available with either 1″ or 2″ process connections. The drain sizes are 1/2″, 3/4″ and 1″ depending on the model selected. The valve actuation pressure range is 30-70 psig (2.06 to 4.82 bar) depending on the model and process pressure. Process pressure rating of up to 2000 psig (137.89 bar)available.

Features

  • Simple Installation – Valve is easily installed with simple hand tools in a short amount of time.
  • Ease of Maintenance – The union nut allows the valve to be removed from service without removing the valve body from the pressure vessel.
  • High Performance Trim Seal – Polyurethane or Polyetheretherketone “PEEK” offer highly durable and long lasting options for sealing the valve from the process.
  • “Keyed” Housing to Valve Joint – Valve is keyed to diaphragm housing to ensure internal retaining hardware does not twist or vibrate loose.
  • Pressure Warning Port – If an attempt is made to remove the valve assembly from the body while the valve is under pressure, process fluid and/or gas will leak from the weep hole to provide a warning.
  • Variety of Trim Sizes – Several trim sizes are available to accommodate different flow and pressure requirements.
  • Powder Coated Finish – The aluminum diaphragm housing is powder coated to provide a durable and resilient finish.
