Design Features
- MSV Piston Valve is basically Seatless and Glandless Valve and by virtue of its design can replace both, the conventional type of Gate & Globe valves. with distinct advantages over them.
- Piston Valve works on the principle of Resilient rings in conjunction with a Metallic Stainless Steel Piston, that moves vertically between the rings. giving a Seal that is both effective as well as Durable. This sealing system gives a bubble tight shut off.
