Gauge Isolator Valve
The Demcon Gauge Isolator Valve is a manually-operated, spool-type hydraulic safety device. Its primary purpose is to protect sensitive pressure gauges and manometers from the destructive effects of continuous system pressure, rapid fluid surges, hydraulic shock, and mechanical vibrations.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
Demcon Gauge Isolator Valves are specialized hydraulic components designed by Demcon Fluid Power Industries to safeguard pressure gauges against mechanical vibrations, fluid shocks, and sudden pressure surges. These valves function as high-pressure shut-off blocks, completely isolating fluid from the dial mechanism until an operator initiates a reading.
| Specification / Feature | Technical Detail |
|---|---|
| Max Operating Pressure | Up to 3000 PSI (210 bar) standard; custom seat-type models handle up to 350 bar. |
| Port & Connection Size | 1/4″ BSP Female threads standard across all active fluid entry and exit channels. |
| Operating Temperature | Rated for extreme industrial environments from -30°C up to 80°C. |
| Fluid Compatibility | Optimized for mineral-based hydraulic oils (viscosity range: 10 cSt to 380 cSt). |
| Body Material | Heavy-duty cast iron or mild steel body built for high-pressure durability. |
| Internal Components | Hardened, precisely ground, and lapped carbon steel spool with Nitrile sealing. |
| Built-in Snubber | Integrated 0.8mm internal orifice to dampen hydraulic shocks and fluid surges. |
| Automatic Drain | Spring-loaded spool automatically isolates pressure and bleeds gauge fluid to the tank upon release. |
| Station Configurations | Available in Single-Station or Multi-Station Manifolds (2, 3, 4, and 6-circuit monitoring). |
| Actuation Options | Standard Push-to-Read (spring return) or Twist-to-Lock (continuous monitoring). |
