Two-way diaphragm valves feature a variety of intelligence
Irvine, Calif. -Two-way diaphragm valves from Burkert are available with intelligent On/Off and continuous proportional control, or manual control. Available in either plastic or stainless steel, Types 2030/2031 are designed for automated process control and Types 3232/3233 for manual control applications requiring two-way flow control of ultra-pure, sterile, aggressive, or abrasive gases, slurries, and viscous fluids.
Diaphragm valve options include a double acting actuator without spring return, flanged connections, Tri-Clamp connections, electrical position feedback, magnetic-inductive proximity sensors for position indication, adjustable stroke limiter, manual override, and custom pilot valve mounting.
A self-draining design with small dead volume makes all models suitable for use in chemical, food, paper, steel, mining, pharmaceutical, and other processes where positive shut-off, non-contamination, and/or ease of maintenance is required.
The 2030 diaphragm valve consists of three variable modules: the valve body, the pneumatic actuator, and the TOP Control assembly or pilot valve. The Type 2030 valve body is constructed of corrosion-resistant PVC or PVDF and is fitted with process connections including true-union, NPT, or butt-weld of 9/16-inch. to 2-inch. Diaphragm material options of EPDM or PTFE/EPDM ensure hermetic isolation between the valve body and actuator. Type's 2030 and 3232 temperature/pressure ratings are 32 to 140°F (0 to 60°C) and 0 to 140 psi (0 to 9.65 bar). The Type 2031 and 3233 are pressure rated for 0 to 140 psi (0 to 9.65 bar). The temperature rating of the Type 2031 is 14 to 284°F (-10 to 140°C) and the Type 3233 is 14 to 266°F (-10 to 130°C).
