( Brand: Marshall Excelsior ), ( Manufacturer Part Number: MEH225 ), ( Type: Relief Valve )
The Marshall Excelsior MEH225 MEC MPT 440 hydrostatic propane relief valve is a critical safety component designed for use in propane fueled hydrostatic transmission systems. This relief valve is engineered to ensure the safe operation of industrial equipment, such as lawn and garden machinery, golf carts, and construction equipment, by preventing excessive pressure build-up within the system.
The valve body is manufactured from ductile iron, a robust material known for its high tensile strength and resistance to wear and corrosion. This ensures that the valve can withstand the rigors of industrial use for an extended period. The pressure relief valve is further strengthened with a hardened brass valve seat, providing added durability and sealing capability.
The valve is outfitted with a diaphragm-operated design, which offers several advantages over other relief valve designs. The diaphragm is constructed from an elastomer material that is resistant to oil and fuel, preventing contamination of the diaphragm and providing consistent performance even in harsh environments. Additionally, the diaphragm allows for easy maintenance as it can be replaced without disassembling the valve body.
The Marshall Excelsior MEC MPT 440 hydrostatic propane relief valve features a temperature-compensated spring design. This innovation ensures that the valve activates at the correct pressure, regardless of ambient temperature changes, keeping your equipment safe and efficient.
Installation is straightforward, with the valve compatible with ANSI flange connections and capable of handling working pressures up to 440 psi (30 bar). Its compact design is well-suited for tight spaces and fits perfectly in applications where space is at a premium.
In summary, the Marshall Excelsior MEH225 MEC MPT 440 hydrostatic propane relief valve is a reliable and robust safety component designed specifically for use in propane fueled hydrostatic transmission systems. With its durably constructed body, diaphragm-operated design, and pressure and temperature compensated spring, it offers the reassurance of consistent performance and maximum safety for your industrial equipment.
