Masoneilan 78-40 air gas Air Filter 1/4NPT Pressure control automatic voltage pressure regulators

1. Description

    The 78 Series pressure regulators are compact, lightweight,  high-performance pressure-reducing valves. They are used primarily for supplying a stable source of air to process control equipment such as current to pneumatic transducers and control valve positioners.

2. Features

    • Excellent pressure regulation. 

    • Lock screw ensures output pressure remains at the desired value. 

    • Small size and light weight allow the regulator to be nipple mounted in most installations, eliminating the need for a mounting bracket. A mounting bracket is available if required. 

    • Two pressure gauge ports allow installation of a gauge on either side for flexibility when mounting. 

    • Soft seat plug on main valve provides positive shutoff. 

    • Sintered polyethylene filters provide a 5-micron filtration rating. 

    • Stainless steel drain. 

    • Corrosion-resistant finish and stainless assembly hardware permit use in corrosive environments.
