Type 2712 - Pneumatically operated 2-way Globe Control Valve

Type Description

The 2712 system has been specifically engineered for reliable control in applications where control accuracy is paramount. The 2712 is made from an all stainless steel valve body combined with Burkert’s classic pneumatic actuator. Each globe valve body can be fitted with three to five sizes of trim sets. These parabolic trims provide a reliable and repeatable characteristic to vary the flow. The control cones are available in either stainless steel or with a durable PTFE seal for tight shut-off. When actuated by the 8635 SideControl, SideControls 8792/93 Remote versionsor the 8694/8692/8693/ 8630 TopControl it forms a unique control valve system which can be operated as either a simple accurate positioner or an autotune PID process controllerfor flow, temperature or pressure.

（1）Excellent control characteristics with compact housing

（2）High life ycle and variability by removable trim kits

（3）Robust actuator with modular accessory program

（4）Stainless steel housing with flange, thread or weld end connection

（5）High operative safety
