Where MARS valves go to work
MARS Valve Co., Ltd is an ISO 9001 certified manufacturer of stainless steel ball valves, tested to the API 607 4th Edition fire-safe standard. That combination of build quality and fire-safe certification is why MARS valves are specified across demanding process and industrial environments worldwide.
Oil & Gas / Refining
MARS ball valves are tested to the API 607 4th Edition fire-safe standard, one of the most demanding fire-test protocols in the industry. That rating matters most where it's needed most: upstream production, refining, and processing lines where a valve has to keep sealing even if the line around it is on fire.
Chemical Processing
Chemical plants move corrosive, high-purity, or hazardous media through miles of pipework, often at extreme temperatures and pressures. Stainless steel construction and fire-safe sealing give operators a valve that holds up to aggressive media without becoming the weak point in the line.
General Machinery
From compressed air and hydraulic circuits to process skids and OEM equipment builds, general industrial machinery depends on valves that are consistent batch to batch — so equipment builders can design around a known, repeatable spec.
Power Generation
Power plants run continuously, often for years between planned outages. Isolation and control valves in steam, cooling, and auxiliary systems need to hold a seal reliably under sustained thermal cycling and pressure.
Water Supply
Municipal and industrial water systems call for valves that resist corrosion over long service lives with minimal maintenance — stainless construction is built for exactly that kind of long-duty, low-intervention use.
Marine & Shipbuilding
Onboard piping — fuel, ballast, cooling, and fire main systems — operates in a corrosive marine environment where a valve failure isn't a quick fix. Reliability and corrosion resistance are non-negotiable at sea.
