It is virtually unaffected by corrosive media such as acids and bases. The uniquely designed ribbed disc creates many small vortex trails that dissipate quickly after exiting the valve and it yields lower pressure drop and noise level than conventional unribbed discs. Lower pressure drop allows use of smaller actuators for a less expensive and more compact total package. Ph stainless steel one piece thru-shaft design ensures reliability and positive disc positioning. EPDM seat assures tight shut-off while providing resistance to corrosive and abrasive material.
All sizes meet industry face to face standards allowing simple retrofit.
Deionized water, Methane gas. Two O-rings provide redundant shaft sealing between valve and actuator. Positive positioner, 60' maximum disc rotation. Gateway also distributes Dwyer Instruments , .
