Special Safety Valve for Viscous Fluids

The S2000 is specially designed for optimum safety and reliability with highly viscous fluids and polymers including polypropylene, polyethylene, rubber and others. Unlike a standard valve the S2000 is engineered such that the polymer only runs inside the pipe thereby preventing blockages.
