True Union
The Type 233 series pneumatically actuated ball valves have the same features and benefits of the +GF+ Type 546 manual valves. The Type 233 is the ultimate choice for the high demands of the industrial world. It is available in PVC, CPVC, Polypropylene and PVDF material. The valve can be configured for throttling or for simple open/close functionality. The optional declutchable manual override is ideal for applications where emergency operation of the valve is required. Additionally, the electro-pneumatic positioner, stroke limiter, and feedback switches give flexibility for integration into a wide variety of applications.
Hayward True Union Ball Valves are superior performers. A fine-pitch seal retainer thread allows for accurate compensation for seat wear. Reversible seats make it easy to get a damaged valve back in service. Should the seats become damaged, they only need to be removed, turned over, and re-installed to put the valve back on line. These valves feature a double o ring stem seal for twice the leakage protection of valves with only a single stem seal. Hayward’s manual True Union Ball Valve has been designed so that it can easily be converted to an automated valve in the field. To do this, just remove the compression fit handle and install an actuator mounting bracket.
