Plast-O-Matic Valve's new thermoplastic check valve prevents reverse flow of highly corrosive and ultra-pure liquids. The check-valve's diaphragm provides normally closed operation with a bubble-tight seal. The multi-port manifold valve is available made from PVC, natural polypropylene, and other thermoplastics. Performance of the valve is not dependent on gravity or mounting position. Available connections include threaded, socket, spigot, flare, and O-ring face fittings.

Burkert's Type 2031 diaphragm valve, when combined with the company's 8045 insertion magmeter, provides continuous flow measurement and batch control of fluids. A built-in electrical connection between the sensor and the valve eliminates the need for wiring from a PLC to sensors and actuators. On/off and continuous pneumatic control loops are available for flow requirements in chemical and food processing applications.
