High Pressure Bonnetless Gate Valves

JIEYU VALVE manufactures superior cast body, bolted bonnet OS&Y gate valves in a variety of materials, trims, packing types, sizes (2" thru 48") and pressure classes (150 thru 2500). The mechanical characteristics make the JIEYU wedge gate valve are ideal for bi-directional "total flow system open/shut-off" applications with minimal turbulance and pressure drop.

The valve design conforms to API 600 and B16.34. Face-to-face and end-to-end dimensions conform to ANSI B16.5 and B16.25.

Gate Valve Benefits

• Little friction and minimal drop in pressure when fully opened
• Eliminates leaks
• Rising stem configurations make visual inspections easy
• Nonrising stem configurations are ideal for areas underground or where space is limited
• Increase efficiency by saving energy when opening or closing a gate valve
