- Renewable seat ring or Body seat ring
A OPERATION: handwheel, bevel gear, motorized actuator, and pneumatic actuator available for a specific application.
B PACKING LOAD: standard bolted packing load or live load with Belleville springs for application requiring frequent cycling o with high temperature and pressure variations.
C OS&Y: outside screw & yoke, yoke integral with bonnet for smaller size, split yoke for a bigger size.
D BONNET: standard bonnet bolted, welded bonnet for option.
E END CONNECTION: flange (RF, RTJ) o Butt-weld
F YOKE SLEEVE: Furnished in aluminum bronze to reduce operating torque. Most size furnished with ball bearing yoke sleeves.
G PACKING: lantern ring and double packing stack are available for critical service.
H BODY-BONNET JOINT: flat face gasket joint for 150lb valves; male and female joint for 300lb & 600lb; ring joint for 900lb & higher
I DISC: Plug disc is stem-guided for all sizes. Disc has a differential angle front the seat to provide linear contact for maximum sealing. The bottom of the v-port disc is guided by the body seat ring for maximum disc stability in throttling applications; the soft Teflon ring is excellent for lower temperature service were a tight shut off required.
J SEAT RING: Separate heavy-duty, full ported rings for easy maintenance. Screwed or welded connection into the body.
WHAT IS A GLOBE VALVE?
Globe valves are linear motion closing-down valves, where the member of the closure is moved squarely on and off the seat. The closure member is usually referred to as a disc, regardless of shape. The opening of seats varies in direct proportion to the disc’s travel. This proportional relation between valve opening and disk travel is ideal for duties involving flow rate regulation. Globe valves are best suited for throttling and fluid flow control and are generally used in small-sized piping.

BOLTED BONNET CONNECTIONS
One of the easiest and least costly designs is the bolted (also called screwed-in) bonnet. The bonnet gasket, however, has to accommodate rotating faces, and repeated de-screwing of the cap can damage the joint faces. Also, for the higher size valves, the torque needed to tighten the bonnet joint is very big. We make premium quality bolted Bonnet Globe Valves which are according to international standards. We are the leading bolted Bonnet Globe Valve supplier of China.
