The Masoneilan Models 78-4 & 78-40 Series pressure regulators are designed as compact, lightweight, and high-performance valves for pressure reduction. Their primary application is to provide a consistent air supply to process control equipment, including pneumatic transducers and control valve positioners.

 

Advantages 

• Outstanding pressure control.
• The locking screw guarantees that the output pressure remains at the specified level. 
• Compact size and lightweight design enable nipple mounting in most setups, thus negating the necessity for a mounting bracket; however, a mounting bracket can be provided if needed. 
• Two ports for pressure gauges facilitate installation on either side, offering flexibility in mounting options. 
• The main valve features a soft seat plug that ensures a reliable shutoff.
• Sintered polyethylene filters deliver a filtration rating of 5 microns.
• Equipped with a stainless steel drain. 
• A corrosion-resistant finish and stainless steel assembly components allow for use in harsh environments.
