Product Details:

A 2 Way R Type Manifold Valve made from Duplex Stainless Steel is a high-performance valve designed primarily for remote mounting in instrumentation systems. It is used to control fluid flow by allowing isolation or venting, commonly for differential pressure transmitters and gauge connections.

• Type: 2 Way R Type (Remote mounting)

• Material: Duplex Stainless Steel (e.g., UNS S32205 or S31803)

• Function: Typically includes 1 Isolation Valve + 1 Vent or Equalization Valve

• End Connections: Usually 1/2" NPT (Female), BSP or metric threads available

• Pressure Rating: Typically up to 6000 PSI (414 bar) or higher depending on design

• Temperature Range: Approximately -40°C to 300°C (depends on packing material)

• R Type: Remote mounting, suitable for impulse line connections

• Duplex Stainless Steel: Offers superior corrosion resistance compared to SS304/316, especially in chloride-rich and corrosive environments

• Double block and bleed functionality (depending on design) allows safe isolation and venting

• Packing: PTFE or Grafoil for high temperature and chemical resistance

• Stem Design: Non-rotating stem tip for tight sealing and longer life

• Tested: API 598, MSS SP-99 standards for pressure tightness and performance

• High strength (about twice that of SS304/316)

• Excellent resistance to stress corrosion cracking and pitting corrosion

• Ideal for offshore, chemical, and seawater applications

• Extended service life under harsh conditions

• Offshore oil and gas platforms

• Chemical processing plants

• Desalination and seawater systems

• Power generation plants

• Marine and shipbuilding industries

• Kalpataru Pipe & Fittings

• Valve Configuration: 2 valves – 1 isolation (block) + 1 vent

• Design Types:

  • Remote Mount (R-Type) – Pipe-to-pipe connections

  • Direct Mount (T-Type) – Instrument mounting interface

• Connections: Threaded (NPT / BSP / BSPT), flanged, or compression ends

• Operation: Manual needle valve with T-bar or round handle

• Pressure Rating: Up to 6000 PSI (414 bar)

• Temperature Range: Up to 500°C (with graphite packing)

• Compact and robust body

• Leak-tight shutoff with precise needle valve operation

Properties of Inconel 625:

Advantages of Inconel 625 for manifold valves:

• Resists pitting, crevice corrosion, and stress corrosion cracking

• Maintains mechanical strength at elevated temperatures

• Provides long-term durability in aggressive environments

A Three-Valve Manifold consists of:

1. Two Block Valves (High & Low Pressure)

   • Isolate the instrument from process pressure.

   • Ensure safe maintenance and calibration.

2. One Equalizing/Bypass Valve

   • Balances pressure across the differential pressure transmitter.

   • Prevents instrument damage during zeroing or calibration.

Key Features:

• Body Material: Forged or bar stock Inconel 625

• Seats: Metal-to-metal or soft seats (PTFE, PEEK) for leak-tight sealing

• End Connections: Tube compression (1/4″–1″), NPT, BSP, or flanged

• Operation: Handwheel, lever, or optional pneumatic/electric actuator

1. Isolation: Block valves shut off process lines from the instrument.

2. Equalization: Equalizing valve balances pressure across high and low sides.

3. Bleed: Vent valve safely releases trapped fluid.

4. Maintenance/Calibration: Instruments can be serviced or calibrated without interrupting the process.

Flow Path Illustration (Simplified):

• High-pressure side → Block valve → Instrument port

• Low-pressure side → Block valve → Instrument port

• Equalizing valve → Connects high and low sides for zeroing

• Differential pressure transmitters in chemical, petrochemical, and oil & gas plants

• Marine and offshore instrumentation

• High-pressure or high-temperature fluid systems

• Monitoring of process lines, tanks, and reactors
