Pressure Seal Globe Valves

Key Application(s)

• For application in fields such as the electric power industry, petroleum, tap water engineering in urban construction, chemical engineering, and others.

Design Features

• Sizes from NPS 2” to 24”(DN50 to DN600)
• CLASS 600 to 2500 （PN100 to PN420）
• Operating temperature -29℃ to 593℃ (the range of service temperature may vary for different materials)
• The sealing faces of the valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of the valve.
• The friction between sealing faces is smaller during opening and closing, facilitating a longer service life.
• The valve clack is of taper, needle, ball and parabola types, and can be used to adjust the flow rate.
• The pressure self-sealing is adopted between the valve body and bonnet for reliable sealing, where the higher the pressure is, the better the sealing performance would be.
• Rising stem structure, making the valve switch position be clear at a glance
• The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced.
• A certain clearance is provided between valve clack and valve stem. You may adjust it by yourself. The sealing is reliable.
• The valve clack can be machined into a parabola, spherical, needle shapes, etc. according to the requirement of the customer. It can be used for adjustment (rough adjustment) on a pipeline.
• The short stroke is suitable for application at positions subject to frequent opening.
• Through improving the structural design and selecting reasonable packing structure and qualified packing supplier, the valves can meet the Class A sealing test requirements of ISO 15848 FE.
