Globe Valves

Conval Bellows Seal Valves are used when packed valves may not reliably contain light gases or hazardous system fluids. The multi-ply Inconel™ static bellows stem seal is more reliable in most applications than sliding stem seals.
Conval Bellows Seal Valves have two back-up stem seals, a graphite packing and a pressure actuated backseat to contain system fluids in the unlikely event of a Bellows rupture.
Meets all the requirements of MSS-SP117. a1029.jpg
For applications with F91 material, extended end connections enable welders to cut back to "virgin" pipe as required.
For applications with Post Weld Heat Treat (PWHT), extended end connections allow for welds further away from the seat. a1044.jpg
Y-Pattern Globe Stop and Stop Check Valves
(48) Y-pattern globe valves provide the maximum Cv possible in a globe valve. All Y-pattern valves are rodable. Available in 1/2" to 4"; ASME pressure classes through 4500; A105, F22, F91, F316, F347, Inconel™, Monel™ and other materials. a1006.jpg T-Pattern Globe Stop and Stop Check Valves
(39) T-pattern, vertical stem globe valves provide easily accessible stems and extensions for remote manual operation. Available in 1/2" to 3"; ASME pressure classes through 4500; A105, F22, F91, F316, F347, Inconel™, Monel™ and other materials. a1009.jpg Angle Pattern Globe Stop and Stop Check Valves
(52) Angle pattern globe valves economically eliminate the need for separate valves and 90º joints. They also reduce the number of installation welds. Available in 1/2" to 4"; ASME pressure classes through 4500; A105, F22, F91, F316, F347, Inconel™, Monel™ and other materials. a1012.jpg Conval Clampseal® API-602 Y-Pattern Globe Valves
(14) Conval Clampseal® API-602 Globe Valves are designed and built for the demanding environments (e.g. pressure and temperature extremes) of onshore and offshore drilling and production, refining, heavy oil and sour gas applications. a1046.jpg Conval Clampseal® API-602 T-Pattern Globe Valves
(13) Conval Clampseal® API-602 Globe Valves are designed and built for the demanding environments (e.g. pressure and temperature extremes) of onshore and offshore drilling and production, refining, heavy oil and sour gas applications. a1047.jpg Conval Clampseal® API-602 A-Pattern Globe Valves
(14) Conval Clampseal® API-602 Globe Valves are designed and built for the demanding environments (e.g. pressure and temperature extremes) of onshore and offshore drilling and production, refining, heavy oil and sour gas applications. a1048.jpg High Pressure Bellows Seal Globe Valves
(18) Packed valves require two different seals: a 360º seal on the stem and a 360º seal on the stuffing box. The Conval Bellows Seal Valve removes these two leak paths.Conval Bellows Seal Valves are used when packed valves may not reliably contain light gases or hazardous system fluids. The multi-ply Inconel™ static bellows stem seal is more reliable in most applications than sliding stem seals.
Conval Bellows Seal Valves have two back-up stem seals, a graphite packing and a pressure actuated backseat to contain system fluids in the unlikely event of a Bellows rupture.

900# Bellows Seal Globe Valves
(9) Lower Pressure (ASME Class 150#-900#) Bellows Seal Valves: Engineered for the demanding environments and regulations of severe service process control. a1031.jpg Special Application Globe Valves
(7) The Clampseal® design is uniquely suited to a number of special applications where service demands require rugged construction while retaining easy in-line serviceability. No other forged valve offers this variety of applications. a1035.jpg Clampseal® Custom End Connection Globe Valves
(9) Custom, extended end connections can simplify the retrofitting of Clampseal® valves to replace other manufacturer's Y-pattern valves.For applications with F91 material, extended end connections enable welders to cut back to "virgin" pipe as required.
For applications with Post Weld Heat Treat (PWHT), extended end connections allow for welds further away from the seat. a1044.jpg
Conval Clampseal® Globe Valves with Actuators
(2) Conval Clampseal® valves are easily adapted to electric motor or pneumatic actuation. Valves ordered with actuators are assembled, functionally tested at Conval and shipped ready for installation, using your preferred brand of actuator. Where customers have existing actuators, the Clampseal® valve is provided with appropriate yoke flange and stem adapter. All actuated valves are furnished with an integral gland wrench. a1042.jpg
