Technical Data Sheet

Outside Screw and Yoke (OS&Y) Gate Valve
(Bronze-Seated, Metal-to-Metal Design)

Product Name: OS&Y Solid Wedge Gate Valve (Bronze Seated)
Standaard: BS5163 / PN16
Maat: DN400 (16 inches)

1. General Design Features

• Type: Outside Screw and Yoke (OS&Y), Solid Wedge, Flanged Ends
• Seat Type: Metal-to-Metal (Bronze Seated)
• Stamontwerp: Rising stem (indicates open/close position)
• Werking: Handwheel Operated (Gearbox is mandatory for this size due to high seating torque of metal seals)
• Sollicitatie: High-temperature fluids, Oils, Steam, Abrasive media, or where rubber is not suitable.

2. Applicable Standards

• Design & Manufacturing: BS5150 / BS5163 (Metal-seated variants often follow BS5150) / EN1171
• Face-to-Face Dimension: EN558-1 Series 3 (or BS2089)
• Flange Drilling: BS4504 / EN1092-2 PN16
• Test & Inspection: EN12266-1 (Rate A or B depending on spec)

3. Technical Parameters

*Note: Temperature range depends on the specific bronze alloy and gland packing material.

4. Main Component Materials

5. Dimensions & Connection Data (DN400 Reference)

*Note: Metal-seated solid wedge valves are often heavier than resilient seated valves. The dimensions below are estimates based on common BS standards. Request certified drawing for exact values. *

6. Critical Notes & Selection Tips

1. “Bronze Seated” Definition:

• This data sheet now reflects a true Bronze-to-Bronze seal. The wedge has a Bronze ring/face that mates with the Bronze seat in the body. This is a metal seat, not a resilient seat.

• Unlike soft-seal valves which rely on rubber compression, metal-seated valves require significant mechanical force to close tightly.
• For a DN400 PN16 metal-seated valve, a gearbox (worm gear) is NOT optional – it is mandatory. Please confirm the gearbox ratio with the supplier.

• Metal-seated valves cannot achieve “zero leakage” (bubble tight) like rubber-seated valves. They typically conform to ISO 5208 Rate D (0.1x DN mm³/s) or Rate E. Please confirm the acceptable leakage rate for your application.

• This bronze-on-bronze configuration is excellent for hot water, steam condensate, and some oil services where EPDM or NBR rubber would fail.

Action Required:
Please confirm with the manufacturer:

1. Gearbox Ratio & Output Torque (Is it suitable for manual operation under max differential pressure?)
2. Sealing Leakage Rate (ISO 5208 Rate D or better?)
3. Flange drilling details (BS4504 PN16) to match your pipeline.
