The Fisher high viscous polymer (HVP) series control valve is used extensively by the polymer industry. These processes generally require the valves to operate at and maintain high temperatures to assure that the polymer fluid flows freely. The HVP valve can provide integral valve body passages through which a heat transfer fluid is pumped to keep the valve and process fluid heated. Forged and fabricated valve body styles are engineered to meet your process and piping requirements. Standard valve body and trim designs can be adapted to exactly match specifications
