Maximum Inlet Pressure: 250 PSIG for Iron/NPT, 300 PSIG for Steel/NPT and Stainless/NPT.
Pressure Ranges: 5–15 PSIG, 15–30 PSIG, 25–75 PSIG, 70–150 PSIG.
Body Sizes: 1/2 NPT, 3/4 NPT, and 1 NPT.
Weight: 1/2" NPT weighs 8 lb (3.6 kg), 3/4" and 1" NPT weigh 19 lb (8.6 kg).

Materials of Construction:

Body, Bonnet, Diaphragm Case Options: Cast Iron, Steel, Stainless Steel.
Diaphragm Options: 302SS, Fluorocarbon, Neoprene, Monel.
Supply Valve Shutoff Options: Metal to Metal, Metal to Elastomer.

Flow Coefficients: Relief sizing coefficients vary by body size, with 1/2" having a Cv of 3.35 and 3/4", 1" having a Cv of 7.80.

Repair Kits: Available for different diaphragm materials including 302SS, Neoprene, Monel, and FKM, with specific part numbers.

Steam Capacities: Detailed capacities for different outlet pressure ranges and body sizes, with offsets for 10%, 20%, and 40% variations.

Pressure Ranges: Nominal body sizes and corresponding outlet or differential pressure ranges, with spring wire diameters and color codes.

Capacities: Lists air and water capacities for different outlet pressure settings and body sizes. Air capacities in SCFH and Nm3/h, water capacities in gallons per minute.

Parts and Materials: Detailed parts lists for different body sizes, including part numbers for components like the body, bonnet, orifice, valve plug, stem assembly, and diaphragm. Materials include 416 SS, 316 SS, brass, and neoprene.

Temperature Ranges: Maximum temperature ranges for body and bonnet materials, as well as diaphragm and seat materials. Cast iron withstands -40°F to +406°F, stainless steel up to +650°F.
