Maximum inlet operating pressure and temperature ratings are 300 PSIG and 150°F. The Dial Regulators are available in five pipe sizes.
Dial regulators feature a transparent, pressure-calibrated, non-rising adjustment dial for quick adjustment of secondary pressure. If a gauge is required for monitoring reasons, two 1/4 NPT gauge ports are provided; however, these are usually used for additional outlet ports. The full reduced pressure range can be dialed in less than 270° of dial rotation. This feature is particularly advantageous if secondary pressure must be changed frequently. The transparent dial can be colour or graphics coded for easy reference to required pressure changes. Dial regulators can be mounted in any position so dial face is always visible. All Dial units have a slight constant air bleed.
