- Wafer and lugged butterfly valves with EPDM or NBR liners, giving quarter-turn isolation in a fraction of the face-to-face length and weight of a gate valve. Lever, gearbox and actuator operation with an ISO 5211 top flange.
- The standard isolation valve on chilled water and condenser water from DN50 upwards, on riser branches, cooling tower lines and AHU coil connections where space between flanges is tight. Lugged bodies are used at the end of a line so the downstream pipe can be removed with the valve still holding pressure.
