Key Features
Engineered and certified to meet BS5150 PN16, BS5163 and EN1171 European gate valve standards, fully compliant for UK and EU industrial and municipal pipeline installations.
Overall face-to-face length adheres to BS 5150 S or EN558.1 F3 dimensional standards for consistent interchangeability across standard piping layouts.
Flange bolt hole patterns machined in line with BS 4504 and EN1092-2 PN16, enabling direct bolt-on fitting with standard PN16 flanged pipework.
Rated nominal working pressure reaches 1.6MPa for steady continuous pipeline operation.
Seat leakage test pressure set at 1.76MPa to guarantee tight shut-off sealing performance.
Body shell hydrostatic test pressure hits 2.4MPa to verify structural integrity against pressure overload.
Max sustainable working temperature capped ≤ 232 ℃. supporting high-temperature steam and hot water service.
Compatible with multiple non-corrosive working fluids including clean water, light industrial oil and inert gas mediums.
1. Built strictly in accordance with the North American industry standard MSS SP-70 for cast iron OS&Y gate valves for US and Canadian piping systems.
2. End-to-end face-to-face sizing follows ANSI B 16.10 Class 125LB/150S dimensions for drop-in replacement of existing ANSI 125LB valve units.
3. Flange drilling layout matches ANSI B 16.1 125LB/150S class, compatible with mainstream American standard flanged pipe connections.
4. Dual pressure ratings apply: 125S/150S for saturated steam operation, 200WOG for water, oil and gas liquid/gas service conditions.
5. Unified integrated yoke and bonnet construction applied across all available valve sizes for stable structural rigidity.
6. Designed to handle common non-corrosive pipeline media: clean water, light circulating oil and low-pressure inert gas.
