Soft Seal Piston Valves are reactor outlet drain valves designed for applications where unrestricted flow, clean discharge, and dead-space-free operation are important. The piston retracts fully into the valve body when opened, helping provide an open flow path through maximized port sizes.
These valves are commonly used for draining, sampling, and injection in powder, slurry, and suspension processes, including PVC process applications.

Hand-operated configurations are available, with options for metallurgy, actuation, vessel connections, and multi-piston positioning.
Soft Seal Piston Valves are engineered to specification and can be adapted for custom process requirements where standard valve configurations may not be sufficient.
