The valves have double seats that are spring loaded for long-lasting drip-tight shut off in both directions even with abrasive medium and independent of a pressure differential between the upstream and downstream side.
Hasteloy, titanium grade 2, stainless steel 304, 316, 317, or SMO254 or others, are materials used for the valves.
The valves are supplied with locking devices LC for mechanically locking the valves in the closed or open position. Longer take-out dimensions than the MSS standard and different configurations of the valve layout are possible for space requirements.
