On Mars Select we feature the Mars Series 83, 88, 90D and 99 range of fire safe ball valves in Stainless or Carbon Steel with a choice of end connection and size for every application. Mars Fire Safe Ball Valves are certified to API 607 4th Edition whereby the valve is fitted with special seats that feature relief slots, designed to. Valves meeting API 607 are designed to inhibit fires that are fuelled by volatile fluid. Basically this standard measures the ability of a ball valve to retard fire propagation. In addition an Anti-Static Device is fitted that comprises of a spring loaded stem to ball and stem to body anti-static device that gives a positive ground.ĪPI 607, Edition 4 was developed by the ‘Refinery Division of the American Petroleum Institute’ (API) and is a fire test for soft seated valves. Such feature typically incorporates a secondary sealing seat that will. We will talk about the ball valve fire safe design from perspectives of internal leakage prevention and external leakage prevention. : 5351/B16.Mars Fire Safe Ball Valves are certified to API 607 4th Edition whereby the valve is fitted with special seats that feature relief slots, designed to relieve pressure upstream and in the event of a fire, contain process fluids within the valve. Most of these high quality butterfly valves are designed with a fire safe feature. and gasket for super-fire-safe provision in accordance with API607 No symbol for PTFE packing gasket. Fire safe design for ball valve is a design that the material and the structure of ball valve can pass a fire test with limited leakage to the atmosphere and downstream after fire exposure. Action: manual, lever & pneumatic actuator.2-way ball and butterfly valves with spring-loaded actuator triggered by thermal or electro-thermal fusible link. Material: ASTM A 216, WCB, CF8, CF8M, 316L etc. Carbon steel or stainless steel 2-way fire-safe butterfly valves.Design: Ball Valve Single Piece Without Fire Safe Blow out proof stem construction.The manufactured products that are portrayed here, includes fire safe fusible link assemblies for emergency shutdown, spring return handles that shut the valves off automatically in case of fire or people forget to shut the valves, and lock-out devices for both automated and manual valve Specifications Damage and insurance costs, while protecting the safety for the plant's employees and the surrounding suburbs.
