Fluid power: Valves
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.
The new Apollo radiant heating valve from Conbraco Industries mixes hot water. The valve has an all-bronze body, stainless-steel springs, brass stem and retainer, and a high-temperature thermostat. The temperature-activated valve has a temperature range between 120 and 180F, but the water inlet temperature range is from 140 to 212F. The maximum working pressure is 125 psi. Standard connections are solder, threaded, union/solder, and union/threaded.
A ball valve from Bee Valve made from glass-reinforced polypropylene is suitable for use with water- and oil-based fluids, chemicals, and some acidic fluids. The valve has a self-aligning ball and a handle that opens and closes it. Its pressure rating is 125 psi.
