The pressure seal globe valve is one type in globe valve,it usually used for high pressure piping line,they are designed in accordance with BS1873 and ASME B16.34 for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service.

The two openings for medium flowing in and out are in the same direction, forming an angle of 180°. In addition, at seat and disc seal surface are over-lay with iron-base alloy or Co-base alloy or carbide alloy for long duration. For large size valves will be designed with main disc and vice disc type, and medium flow from up disc to down disc, that the operation torque will be greatly decreased and the seat tightness performance are more reliable.

• Design standard as per: BS1873,ASME B16.34, GB/T 12235, DIN3356
• Generally, lift of disc is just 1/4 of the valve seat port, ensuring a short opening and closing time.
• Only one sealing face is designed on the valve body and valve disc,
• For large size valves will be designed with main disc and vice disc type, and medium flow from up disc to down disc.
• Full stellite overlay seat sealing surface
• Good for manufacturing process and easy to maintain.
• The valve is designed as a back seat sealing structure.
• Use flexible and woven graphite collaboration type packing(V type).
• Optional by-pass design,
• Top flange size as ISO5211 design easy to install pneumatic actuators and electric actuators.
