• No external power source is required.
• Pressure & temperature pilots can be used in combination, eliminating the need for a separate pressure and temperature regulator.
• Ductile iron body for higher pressure ranges and increased safety when compared to cast iron.
• Full port strainer and blowdown valve on pilot adapter for ultimate protection against dirt and scale.
• Hardened stainless steel trim (55 Rc) for extended life even in the most demanding applications.
• The innovative design allows the pilot to be mounted on either side of the regulator and is easily field-reversible without having to rebend tubing.
