| New large diameter ball valve from GF Piping Systems  GF Piping Systems has introduced the Type 546 Ball Valve in sizes 2½", 3" and 4". The new valve is suitable for use across a broad spectrum of applications including industrial water treatment, swimming pools, aquariums, water parks, waste water technology, potable water treatment, chemical distribution, electroplating and power plants. Available in five materials, Polypropylene, PVC, CPVC, ABS, and PVDF, the Type 546 Valve's multifunction module expands the number of uses by allowing the user to easily add different accessories, actuators and switches.Using the multifunctional module, the new valves can be easily actuated with GF Piping's PA Series of Pneumatic Actuators or EA31 Electric Actuators. The module's electric position feedback switch signals a controller to indicate valve position and also transmits the information remotely, providing an excellent means of monitoring for both control and safety. The module allows a variety of micro switches including Ag-Ni, Au as well as inductive switches with NPN, PNP and Namur signals for optimum versatility. The splash-proof module housing is manufactured of 30% glass-reinforced polypropylene for robust construction and secure mounting. The Type 546 Valve requires minimum torque for operation, allowing for smaller, less expensive actuators. This results in less wear, easier movement and longer valve life. The Type 546 Valve incorporates a number of additional features that provide ease of use and high performance. The lockable handle prevents accidental movement or unwanted manipulation while its ratchet styling permits settings in 5º increments for precise positioning. Other characteristics include stainless steel threaded inserts for easy mounting, a smooth ball surface that prevents formation of deposits, and a special backing seal that ensures tight sealing, even with water hammer. write your comments about the article :: © 2006 Construction News :: home page |
