Stockham Butterfly Valves

Many years of valve experience have been incorporated into the design and production of Stockham butterfly  valves. The simplicity of design, ease of installation and low installed cost are just some of the reasons for such  wide acceptance of these valves. The same quality that is built into all Stockham valves ensures the user that our butterfly valves will continue to be proven performers.
Stockham butterfly  valves Advantages:
QUALITY MANAGEMENT:
Stockham is committed to a philosophy  of total quality management. It begins with design, assuring compliance  with relevant MSS and ASME standards, and it extends to materials and  services to satisfy our customers' needs.
MATERIALS:
Standard body materials for butter fly valves include cast  iron, ductile iron and carbon steel. Body and trim materials are produced  to conform to the chemical and physical requirements of the American Society  for  Testing  and  Materials  (ASTM). 
RATED  WORKING  PRESSURE:
The  maximum  cold  working pressure for all cast iron butterfly valves is 200 psi for sizes 2"“ 12", and 150 psi on sizes 14"  36".
DESIGN:  RESILIENT,  CARTRIDGE-TYPE  SLEEVE,  WAFER
AND LUG, SIZE 20"
BODY:
Available  in  wafer  and  lug  types,  with  extended  necks  to accommodate  2"  of  insulation.  Face-to-face  dimensions  meet MSS SP-67 and API 609. Bodies are epoxy coated as standard through  12".
Lug body Butterfly valves are recommended for lines where bi-directional deadend service is required for removal of downstream piping for equipment  maintenance purposes. In such cases, our standard lug style valves and  our M-Series contractor valves provide this capability.
STEM:
A one-piece stem design is standard. Standard material is Type 416 stainless steel, with Type 316 stainless available.
Stem  bushings  are  furnished  on  all  valves  to  provide  longer  life  with lower torques.
DISC:
Discs are precision machined to assure tight shutoff.
Standard  disc  materials  are  ductile  iron  (nickel  plated),  aluminum bronze, and CF8M (Type 316 stainless steel).
SLEEVE:
Standard  iron  valves  have  a  cartridge-type,  replaceable sleeve. The  seating  material  is  a  resilient  elastomer  integrally  molded  to  a  rigid  phenolic  backing  ring  which  forms  a  non-collapsible  seat sleeve. Sleeves extend past body faces to provide seal against mating flanges. M-Series valves utilize a molded-in liner which allows these valves to be used for bi-directional dead-end service. Other valves have cartridge type  replacement  sleeves.
