Product description
The Bleed Valve, 1/2 in NPT, 10,000 psi, Sour Service, 316SS Body is a small-bore instrumentation valve, 1/2 in, 1/2 in NPT Female, rated for 10,000 psi. NACE MR0175 / ISO 15156 sour-service compliant.
Bleed valve — a small-bore valve for venting line pressure to atmosphere or to a closed bleed system. Used as the bleed leg of double-block-and-bleed configurations and for instrumentation service.
Construction
- Type: Instrumentation — Bleed Valve
- Nominal size: 1/2 in
- Body material: 316 stainless steel — NACE MR0175 compliant
- Stem / trim: 316SS stem + 17-4PH spindle
- Seal / packing: Graphite + Inconel braided packing (sour)
- Inlet: 1/2 in NPT Female
- Outlet: 1/2 in NPT Female (vent)
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. NACE MR0175 sour-service compliant — material class EE.
Applications
- DBB manifold bleed leg
- Instrument bleed-down to atmosphere
- Drain valve for closed bleed systems
- Instrument calibration vent
Compliance
- API 6A / ASME B16.34 instrumentation valve criteria
- NACE MR0175 / ISO 15156 (sour-service)
- 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.
