Product description
The Gauge Isolation Valve, Single-Block, 1/2 in NPT × 1/2 in NPT, 10,000 psi, Standard Service is a small-bore instrumentation valve, 1/2 in, 1/2 in NPT Female (process), rated for 10,000 psi. Standard service rated.
Gauge isolation valve — a compact valve mounted directly between the process tap and the pressure gauge, allowing gauge replacement / calibration without depressurising the line. Lockable in either open or closed state.
Construction
- Type: Instrumentation — Gauge Valve
- Nominal size: 1/2 in
- Body material: 316 stainless steel
- Stem / trim: 316SS stem + 17-4PH spindle
- Seal / packing: RPTFE back-up + Viton (FKM) primary seals
- Inlet: 1/2 in NPT Female (process)
- Outlet: 1/2 in NPT Female (gauge)
Performance
Working pressure 10,000 psi. Hydrotested at 1.5× working pressure. Operating temperature -50°F to +250°F (-46°C to +121°C) per the data plate. Standard service rated.
Applications
- Pressure-gauge isolation
- Calibration tap-off isolation
- Maintenance bypass for instruments
- General-service gauge installation
Compliance
- API 6A / ASME B16.34 instrumentation valve criteria
- Mill test reports per EN 10204 3.1 / 3.2
How to order
Confirm (a) line working pressure and pressure class, (b) end connections (NPT / integral flanged / autoclave compression), (c) service class (standard vs sour, with H₂S partial pressure data for NACE compliance), (d) handle type (T-bar handle / handwheel / locking lever), (e) any required ATEX / IECEx certifications for hazardous-area mounting. Indus quotes ex-Dubai for stock items and ex-works OEM for build-to-order.
Companion products
Pair with matching pressure transmitters, gauges, and tubing kits for the instrumentation tap-off. Indus also supplies impulse-line tubing (1/2" / 1/4" / 3/8" 316SS), fittings (compression and weld), and matching mounting brackets on request.
