Technical Data Sheet
Product: DN80 – PN40 Flanged Soft Seated Globe Valve
- Product Description
This flanged globe valve features a soft‑seated design, providing excellent shut‑off performance with minimal leakage. The globe valve configuration offers precise flow regulation and reliable on‑off control. The soft seat ensures bubble‑tight sealing, making it ideal for applications where leakage integrity is critical. Constructed with a rising stem and handwheel operator, this valve is suitable for a wide range of industrial services including water, oil, gas, steam, and mild corrosive media.

- Caractéristiques principales
- Soft Seat Design
- PTFE or reinforced PTFE seat insert provides bubble‑tight shut‑off (zero leakage).
- Low friction between disc and seat reduces operating torque and extends service life.
Globe Valve Flow Characteristics- Excellent throttling and flow regulation capabilities.
- Suitable for frequent operation and precise control.
Rising Stem (OS&Y)- Stem threads are isolated from the media, reducing corrosion and wear.
- Visual indication of valve position (open/closed).
Bolted Bonnet Construction- Easy maintenance and access to internal components.
- Reliable sealing with spiral wound gasket.
Optional Features- Bellows seal for zero stem leakage.
- Gear operator for larger sizes or higher pressures.
- Pneumatic or electric actuation for automated control.
- Dimensions & Weight (Reference)
Values are typical for EN 1092‑1 PN40 RF flanges. Final dimensions to be confirmed from certified GA drawings.

- Design & Manufacturing Standards
Standard | Description |
Conception | BS 1873, API 623, ASME B16.34, EN 13709 |
Pressure‑Temperature Rating | ASME B16.34, EN 1092‑1 |
Face‑to‑Face | EN 558 Series 1, ASME B16.10, API 623 |
Flange Connections | EN 1092‑1 PN40, ASME B16.5 Class 300 (as specified) |
Inspection & Testing | API 598, ISO 5208, EN 12266‑1 |
Testing:
- Shell strength test: 1.5 × rated pressure
- High‑pressure seat test: 1.1 × rated pressure
- Low‑pressure seat test: 0.6 MPa (bubble‑tight for soft seat)
- Installation Considerations
- Flow Direction
- Globe valves are typically installed with flow entering below the disc (flow‑to‑open or flow‑to‑close) depending on design.
- Flow direction arrow on the body must be followed to ensure proper sealing and performance.
Orientation- Can be installed in horizontal or vertical pipelines with the stem upright.
- Avoid installation with stem inverted to prevent debris accumulation.
Maintenance- Soft seat inserts can be replaced without removing the valve from the pipeline (with bolted bonnet design).
