What is a D-Type 3-Way Manifold Valve?

A D-type manifold valve is a common 3-valve arrangement used in instrumentation to provide isolation, equalization, and venting/bleeding functions in a compact, integrated design.

🛠️ Typical Features of D-Type 3-Way Manifold Valve:

• 3 valves in one body:

  • Two isolation valves on the inlet and outlet lines

  • One equalizer valve connecting the two lines to equalize pressure

• Usually includes drain or vent ports for safe pressure release

• Valve operation: Needle valves or ball valves, typically with handwheels or levers

• Material: Stainless Steel 316 / 316L for corrosion resistance

• Connections: Double ferrule tube fittings, threaded ports, or flanged connections

🔄 Flow Paths and Functions:

• Isolate valve 1 (upstream): Blocks process fluid

• Isolate valve 2 (downstream): Blocks fluid going downstream

• Equalizer valve (middle): Connects upstream and downstream sides to equalize pressure (used during calibration or maintenance)

• Drain/vent port: Often integrated or available separately for draining fluid or venting pressure safely

Stainless Steel Valve Manifold

A Stainless Steel Valve Manifold is a precision-engineered assembly used in instrumentation and pressure measurement systems to isolate, equalize, and vent pressure instruments such as pressure gauges, transmitters, and differential pressure instruments. Manifolds reduce the need for multiple valve connections and improve system reliability and maintenance.

Made from SS 304 or SS 316/316L, these manifolds offer excellent corrosion resistance, high-pressure handling, and durability in chemical, petrochemical, power, and offshore applications.

📌 Key Features

• Material: SS 304 / SS 316 / SS 316L

• Valve Types: Needle-type or ball-type valves

• Configuration: 2-way, 3-way, 5-way (R-type or T-type), and custom configurations

• Mounting: Pipe-mount, panel-mount, or remote-mount options

• Connections:

  • Inlet/Outlet: 1/4", 3/8", 1/2" NPT / BSP / BSPT / Flanged

  • Instrument: Direct mount or via tubing

• Working Pressure: Up to 6000 PSI or higher

• Temperature Range: -40°C to +450°C (depends on seal material)

📐 Technical Specifications ✅ Advantages

• Compact, integrated design — reduces leak paths and connection points

• Corrosion-resistant stainless steel — ideal for aggressive media

• Safe isolation, venting, and calibration of pressure instruments

• Minimizes downtime and maintenance

• Standardized mounting for gauges and transmitters
