Technical Specification

• Single Seated : Closing with inlet pressure for positive, dead-end, shut-off
• Accuracy of Regulation : Comparable to instrument control with full flow for equivalent pipe
• New type piston with Teflon+Seal : For temperature up to 500 F. Give continuous wiping action keeping liner clean, improving operating reliability and reducing maintenance. Piston rings can be furnished for temperatures over 500 F.
• Fully Guided main valve : Prevents rubbing or binding of internal parts
• Gradual opening ported main valve : In sizes 2 1/2" and larger for improved throttling control under low flow conditions.
• Sensitive stainless steel diaphragm : Responds instantly to any flow change and eliminates stuffing boxes and bellows seals. Full travel less than its own thickness stress to a minimum.
• Renewable Interchangeable parts : Machined to close tolerance; complete overhaul without machining or removing valve body from the line.
