Compact, extremely rugged design. Available in different steel types for the control of a variety of corrosive materials.
Bodies
Heavy and compact. Extra long pipe threads ample clearance over end of pipe to prevent jamming against back wall and choking port.
Carbon Steel Recommended for dry natural or artificial gasses, low-sulfur oil compounds and other liquids and gasses that do not attack carbon steel. Carbon steel parts are given full phosphate treatment for greater corrosion resistance.
18-8 Mo (type 316) stainless steel More resistant to chlorides and organic acids than the usual 18-8 Stainless Steels.
Stem
Thread pitch is extremely fine, providing for close regulation. Large diameter gives extra strength.
Seats
Integral.
