Sample Specification
All thermoplastic modulating control valves shall be of the
globe valve design. Valves shall have interchangeable seat and
plugs to accommodate various flow coefficients (Cv) and flow
characteristics shall be either linear or equal percentage. Stem
seal shall be PTFE and of the bellows design. Electric actuator
shall be constructed of glass-filled polyester (PEG) with stainless
steel trim. Actuator shall operate with 120 VAC/1ph supply
voltage, have a visual position indicator and be capable of on/
off or modulating operation. PVC shall conform to ASTM D1784
Cell Classification 12454-A, PP conforming to ASTM D4101
Cell Classification PP0210B67272, and PVDF conforming to
ASTM D3222 Cell Classification Type II, and PTFE shall conform
to PTFE TFE 1600, as manufactured by Asahi/America, Inc.
