Designed to reduce LP-Gas and anhydrous ammonia container  pressures to between 3 and 125 PSIG. Precision-built with a multi-million BTU capacity, the 1580V series is perfect for such big, tough jobs as crop dryers, asphalt batch mixing plants, road building “tar wagons”, heat treating and other large industrial and commercial loads. It’s also ideal as a first stage regulator in large multiple operations. The AA1580V series is ideal for use in anhydrous ammonia applications such as blue print machines and heat treating.

Types R222, R622, R642, R652, and HSRL Second-Stage regulators are Underwriters Laboratories (UL®) listed regulators designed to reduce the outlet pressure from a First-Stage regulator, usually 10 psig / 0.69 bar to 11 inches w.c. / 27 mbar, in domestic installations. Vents are screened with standard orientation over the inlet, but other orientations are available. Fisher® brand SecondStage regulators are painted palm green for easy identifi cation. Types R222, R622, R642, and R652 are equipped with a stainless steel inlet screen to reduce the  mount of debris entering the regulator and have a temperature rating of -20 to 160ºF / -29 to 71ºC, but have passed Fisher internal testing for lockup, relief start to discharge and reseal down to -40ºF / -40ºC.

Designed to reduce propane gas container pressure down to between 3 and 100 PSIG. Ideal for liquid or vapor service, they can be used in a variety of applications including salamander heaters, weed burning torches, fish cookers, tar pot heaters, and other industrial type services.

Features/Specifications:

• Provides high capacity performance at a reasonable price.
• Suitable for both liquid and vapor service.
• Compact design provides for easy installation.
• Negative or indirect acting design provides for excellent performance when needed most – in cold weather, when tank pressures are lowest and system demands are highest.
• Consistent delivery pressure, especially in cold weather, helps assure maximum performance from the second stage regulator.
• Can be readily fitted with a pressure gauge in the 1/4” F.NPT port.
• Molded diaphragm provides an o-ring like seal between the body and the bonnet.
• Fully painted in brilliant red for complete corrosion protection.
• Available in four adjustable ranges for maximum performance.
• Bonnet and body are assembled in the USA using the unique, patented RegULok™ Seal System.

64 Series adjustable regulators usually reduce tank pressure to an intermediate pressure for use by another regulator. They may be used as high-pressure regulators on distribution systems when used in conjunction with first-stage downstream regulators. When equipped with an internal relief valve (64SR Series), the regulator may be used as a final-stage regulator on high-pressure systems. 64KB Series has a special PTFE diaphragm protector that makes it suitable for anhydrous ammonia NH3 service.
