Aska innovated Ram valve (Piston valve, Ram plunger valve) is a kind of drain valve that has piston (plunger) type disc. It used for drain, flush and dead space free shut-off for reactors, vessels and pipe line etc.

These valves are preferred to Disc type flush bottom valves when full flow is required. Ram valves guarantee full flow. These valves are good enough for slurry application as inside of the valve is cleaned when ram is traveled.

Teflon(R) coating and lining available.
For corrosion resistance, chemical resistance, and adhesion prevention of impurities.
Not only for Polymer, but also Pharmaceutical, food application

Ram valves /Piston valves guarantee full flow as the valve disc (ram) travels completely out of the flow path.
These valves are ideal for slurry applications as the inside of the valve is cleaned when the valve disc (ram) is traveled.
