Metso Automation Launches JAMESBURY G Series Ball Valves for Oil and Gas Applications
NORTHBOROUGH, Mass. (June 29, 2006) - Metso Automation has launched the JAMESBURY G series trunnion mounted, polymeric-seated ball valves, designed to provide excellent tightness over an extensive range of temperatures and pressures. The combination of trunnion mounted balls and a unique spring-loaded upstream sealing capability provides bubble-tight shut off and low operating torques, even at extremely high shut-off pressure.
Available in both full bore and reduced bore designs in a choice of materials, sizes and pressure classes, coupled with conformance to ANSI and NACE specifications, qualify the JAMESBURY
G Series ball valves for virtually all oil and gas services.
The JAMESBURY G series ball valves conform to the requirements of ANSI B16.34 and API 6D. They are manufactured under a quality plan that complies with the requirements of API Q1
and ISO 9001.
The standard valve uses forged steel as the body material which eliminates unavoidable defects of castings and assures uniform tough structure of the valve at full rated working pressure. The wide choice of quality trim materials makes the valve durable even under severe conditions.
The trunnion mounted ball in JAMESBURY G series ball valves prevents high upstream
pressures from forcing the ball into the seats producing high seat loading and high operating
torque requirements.
The unique spring-loaded floating seats provide upstream sealing regardless of flow or pressure direction. These seats provide bubble tight sealing at both high and low differential pressures. Leak testing is performed to the requirements of API 6D or API 598.
While JAMESBURY G series ball valves do not require lubrication under ordinary circumstances, they feature a secondary sealant injection system for stem seals. Additionally, a seat injection system is a standard feature on valves 6" or larger. These systems are provided only to enable the customer to provide a temporary seal in the event of damage.
The JAMESBURY G series ball valve has been fire-tested in accordance with API 607
and BS 6755 part 2.
Spring loaded upstream and downstream seats and body drains allow the valves to be used in double block and bleed service without modification.
Carbon steel stems, balls and seats are electroless nickel plated as standard. A wide range of alloys are available for corrosive services. The JAMESBURY G series ball valves are supplied as standard in materials that meet the requirements of NACE MR-0175. Strict material control and inspection during the manufacturing process ensures compliance.
Valves, sizes 2" to 4", Class 150, 300 and 600, 2" and 3" Class 9000 and 2" class 1500 are operated with lever handles. Larger size valves are supplied with gears. The JAMESBURY G series ball valve can be supplied with pneumatic, hydraulic or electric actuators for automatic operation.
When valves are to be installed below ground level, extensions for the stem and actuator mounting pad are available. Extensions for sealant injection fittings and drain and vent fittings are also provided. Customers must specify the required extension length.
