1. General Description

• Product: Flanged End, Outside Screw and Yoke (OS&Y), Solid Wedge Gate Valve
• Seat Type: Bronze-to-Bronze Metal Seated (Metal-to-Metal)
• 작업: Bevel Gear Actuator with Handwheel and Mechanical Position Indicator (visual open/close indication)
• 설계 표준: BS 5150 / BS 5163 (Metal-seated variant)
• Ends: Flanged to BS 4504 / EN 1092-2
• 대면: BS 2089 or EN 558-1 Series 3 (short pattern)
• Test Standard: BS 6755 / EN 12266-1

2. 애플리케이션

• Suitable for: Water, steam, oil, gas, and other non-aggressive fluids where metal-to-metal sealing is required.
• Temperature Range: -10°C up to +200°C (depending on packing and bronze alloy)
• Pressure Rating: PN10 / PN16 (specify as required)

3. Technical Parameters (Typical for DN200 PN16)

(For other sizes, refer to Section 7.)

4. Materials of Construction

5. 특징

• Gear Operation: Smooth and low torque operation even under high pressure; suitable for large valves and frequent use.
• Position Indicator: Clearly shows valve open/closed status; ideal for buried or inaccessible installations.
• Bronze Seated: Superior corrosion resistance and long service life in demanding fluids.
• Rising Stem: Visual confirmation of stem position (OS&Y design).
• In-Line Repairable: Packing can be replaced under pressure when valve fully open.

6. Dimensions & Weights (Reference Values – DN200 PN16)

(For exact dimensions, refer to manufacturer’s drawing.)

7. Dimensions for Other Common Sizes (PN16) – Reference Only

*(Face-to-face per EN 558-1 Series 3; flanges per EN 1092-2 PN16. For PN10 dimensions, consult supplier.)*

8. Gear Operator & Position Indicator Details

• 유형: Fully enclosed worm gear unit
• Ratio: Typically 20:1 to 40:1 (depending on size)
• Input Torque: Designed for comfortable manual operation
• Indicator: 0–90° movement flag type; clearly marked “OPEN” / “SHUT” or with local visual disc/flag
• Housing: Coated cast iron or aluminium, weatherproof

9. 테스트

• Shell Test: 1.5 x PN (24 bar for PN16) for duration per EN 12266-1
• Seat Test: 1.1 x PN (17.6 bar for PN16) with allowable leakage per Rate D (or tighter if specified)
• Optional: High-pressure seat test, low-pressure air test, or zero-leakage resilient seat tests available on request.

10. Notes & Selection Tips

1. Bronze Seated: Ensure the application does not require zero-leakage bubble tight shut-off; metal seated valves have allowable leakage.
2. Cast Iron Limitations: Avoid thermal shock or rapid temperature changes; not suitable for flammable or toxic fluids without specific approval.
3. Gearbox: Standard with handwheel; optional chain wheel or electric actuator available.
4. Position Indicator: Provided as standard with gear operator; if handwheel only, indicator may be optional.
5. Flange Standard: Confirm whether BS 4504 (metric) or BS 10 (inch-based) is required.

11. Ordering Information

To ensure correct selection, please specify:

• 크기(DN)
• 압력 등급(PN)
• Flange Standard (e.g., BS 4504 PN16)
• End Use / Medium
• Any special test requirements
