Valve-Internal 1-1/4Strtthru Bdy Remltch

All FISHER internal valves are suitable for LP gas or NH3 service. Special construction is availble for other compressed gases. All of FISHER's threaded internal valves have a compact, one-piece body design. They can be actuated manually, by cable control or with an air cylinder. FISHER offers the widest variety of threaded internal valves in the industry. While their most frequent use is in the liquid and vapor openings of bobtail and transport trucks, the valves can also be used in stationary storage tanks, complying with NFPA 58 requirements. Designed as primary shutoff valves, the units include several features that help control product discharge. Steel and stainless steel construction are standard throughout with total stainless steel construction available. The valves have spring-loaded PTFE packing for an effective seal against leakage. Standard disc material is Nitrile (NBR), but PTFE, Perfluoroelastomer (FFKM) and Fluorocarbon (FKM), Ethylenepropylene (EPDM) and Neoprene are available. (Note: PTFE seats are not bubble tight.)
