Burkert Type 2712 and Type 2012 Globe Valves Enhanced —Larger Flange Size, Greater Rangeability Among Improvements

Burkert Type 2712 and Type 2012 Globe Valves Enhanced —Larger Flange Size, Greater Rangeability Among Improvements
Irvine, Calif., November 15, 2002 — Burkert announces that it has improved its family of pneumatically operated globe valves: The Type 2712 Intelligent Globe Control Valve now is available up through 4-inch flanged, with 50:1 rangeability and three trim sizes. The Type 2012 ON/OFF Globe Valve also is now offered up to 4-inch flanged, and has been engineered so its lifetime far surpasses ball and butterfly valve lifetimes.

Burkert is highlighting the Type 2712 and Type 2012 Globe Valves at the Allen-Bradley Automation Fair 2002 in Anaheim, Calif., November 20-21.

The new 4-inch flange end connections means Burkert now is able to offer the Type 2712 and Type 2012 in a broader range of sizes, increasing the globe valves’ versatility. Previously, the Type 2712 and Type 2012 were available up to a 2-inch flange and NPT end connections.

The 50:1 rangeability and three trim sizes available for the 2712 allow greater flexibility in accurately controlling each customer application while maintaining appropriate line velocity. The electronic positioning arrangement, with no hysteresis in positioning linkages, ensures fine position control, low deadband and excellent repeatability.

The Type 2012 features the same piston actuator used in Burkert’s Type 2000 Y-Pattern Angle Seat Valve; this linear motion valve is field-proven for 5 million cycles. Conversely, ball and butterfly valves have typical lifetimes of 250,000 to 500,000 cycles.

Details: Type 2712 and Type 2012 Globe Valves
The Type 2712 and Type 2012 globe valves handle neutral and aggressive fluids, gases and steam up to 150 PSI/365°F in high-end process applications, and are available in ANSI flange, threaded port, tube weld end and Tri-Clamp® configurations (316L cast stainless steel bodies). Both valves are used extensively in the pharmaceutical, water treatment, food/beverage, textile, cosmetics, chemical, pulp/paper, and biotech industries.

The Type 2712 and Type 2012 connect directly to a full range of Burkert TOP Control systems, intelligent sensors and valves. For example, the Type 2712 can employ the following Burkert units as valve actuation systems: Type 8630 TOP Control (electro-pneumatic valve actuation device), Type 1067 SIDE Control (three-wire process controller/positioner), and Type 8635 SIDE Control (two-wire electro-pneumatic process controller/positioner).

Meantime, the Type 2012 can implement the following Burkert units as valve actuation systems: Type 6012/6014 Banjo Valves (pneumatic single-pilot valves), Type 5470/6519 NAMUR Valves (highly reliable switching, diaphragm-driven seat valves), and Type 8633 Mini TOP (combines pilot valves/position feedback in an integrated, compact design).

Both the Type 2712 and Type 2012 are designed to reduce Total Cost of Ownership by up to 80 percent. The valves are configured for networking in centralized or decentralized process control systems, and are ASi-, PROFIBUS- and DeviceNet-capable.
