ST-261 SI Unloader Valves w/ Chemical Injector & Micro Switch
 |
| Applications: |
Features: |
| Used for adjusting the maximum working pressure and safe guarding the high pressure water pipes. Ideal for steam combination applications. Low pressure limit eliminates need for additional metering devices.
|
- Only tamper-resistant operator adjustable valve in the industry which allows limit setting on both maximum pressure and minimum pressure.
- Straight flow-through design minimizes pressure loss through valve.
- Working components constructed of high-grade stainless steel. PTFE and Viton™ seals for maximum heat and chemical resistance.
- Internal bypass valve can be easily accessed and repaired without removing unloader from unit.
- Built-in exclusive down stream (venturi-type) injector with built in orifice provides more precise siphon rate.
- 500 PSI MIN
