WKM | pow-r-seal
The WKM Pow-R-Seal expanding gate valve is one of the most trusted gate valves, especially where safety and seal reliability are critical.The positive mechanical seating force of the lock-in-place seals holds with zero leakage through conditions of vibration, pressure change, and temperature excursion. The rigid, cast steel body resists pipeline bending moments.
LVS | SUP-R-SEAL
The LVS SUP-R-SEAL gate valve is a through conduit expanding gate valve. The expanding gate of this valve provides a tight seal that holds up to most pressures with a variety of flow mediums. The seats are equipped with plastic sealing surfaces to provide the best seal for multiple mediums, pressures and temperatures.
