Product Overview
Newterra’s Multiport Relief Valves are designed for advanced pressure control and safety in industrial systems, offering a reliable solution for managing overpressure conditions and ensuring operational integrity. These valves feature a multiport design that allows for precise pressure relief, enhancing system safety and performance. Engineered for durability and efficiency, they are suitable for a wide range of applications, including water, steam, and gas systems. The valves’ robust construction ensures long-term reliability and resistance to wear, while their ease of maintenance and adaptability to different system requirements make them a versatile choice for industries seeking to optimize their pressure management and safeguard their infrastructure. Newterra’s Multiport Relief Valves embody the blend of innovation and reliability essential for modern industrial operations.
Features
Multiport Relief Valve Springs cannot be compressed solid nor can the valve be locked closed by external adjustment. When springs are compressed to a maximum point by handwheel adjustment, the valve discs will open upon overpressure. Operating components are internal to the valve, which precludes tampering.
Designed for maximum safety. The valve and springs are designed for the maximum initial relief pressure indicated on the nameplate. This pressure cannot be exceeded by external adjustment even though the valve is fully adjustable to all pressures within the zero to maximum pressure.
Installation should follow every pressure-reducing station on all low-pressure exhaust steam systems using supplementary reduced live steam. This will provide absolute protection should the reducing valve fail in the open position.
Multiport Relief Valves are provided with multiple resilient surfaced vapor cushion discs (on standard brass trim valves) which are non-popping, cushion lift, cushion closed and tight reseating. The seating surface, an extremely resilient high-temperature thermoplastic material, allows movement yet helps provide a reliable “soft seal” that prevents leaking. Since this piston seat and disc assembly seats without leaking and reseats faster than other types of assemblies, useful steam is never wasted. The net result is a reduction of operating costs by saving steam.
