Technical Specifications
| 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; continuous wiping action keeps liner clean, improves reliability, reduces maintenance. Piston rings available for >500°F. |
| Fully guided main valve | Prevents rubbing or binding of internal parts. |
| Gradual opening ported main valve | In sizes 2½” and larger for improved throttling control under low-flow conditions. |
| Sensitive stainless steel diaphragm | Instant response to flow changes; eliminates stuffing boxes and bellows seals. Full travel less than its own thickness to minimize stress. |
| Renewable interchangeable parts | Close-tolerance machining allows complete overhaul without machining or removing the body from the line. |
