Features include: Valves available from 1 PSIG through 29 PSIG with a calibrated ½ PSIG increment per removable disc; Anodized Aluminum construction for years of trouble-free service; Models have standard MPT connections; High flow-through capacity.
Advantages: Minimal maintenance required; Simple operation. Line pressure naturally displaces the weighted cap upwards and off the valve seat. As the pressure increases, the valve exposes more vent area for higher flow; Valve automatically seats itself when the pressure is removed; All operating surfaces are machined and the entire valve is heat treated and anodized for the highest quality; Retainer ring ensures valve settings are not tampered with; Simple method of opening and closing insures that the valve is virtually chatter-free.
