The High Temperature Steam Thermal Oil Manual Bellows Stop Valve is a premium fluid control valve from RICK VALVES, exclusively engineered for high-temperature and high-pressure industrial systems such as steam and thermal oil pipelines. As a specialized bellow-sealed valve, it features a unique metal bellows design that fully isolates the valve stem from the internal fluid, eliminating stem leakage and media contamination— a critical advantage for extreme operating conditions where reliability and sealing are non-negotiable. Established in 2006, RICK VALVES manufactures this valve with state-of-the-art CNC machining and non-destructive testing equipment, complying with BS 1873 and ASME B16.34 international standards. Available in straight, angle and throttle structural types, with manual operation as standard and electric/pneumatic actuation options, this bellows stop valve delivers smooth, precise flow control with minimal maintenance, making it the ideal choice for industrial systems handling steam, thermal oil and other high-temperature media. It is built with high-grade alloy and stainless steel materials, ensuring exceptional durability and leak-free operation even under continuous extreme working conditions, and holds ISO 9001:2015 quality certification for consistent manufacturing standards.
The integrated metal bellows design is the core of this valve, isolating the valve stem from the internal fluid to prevent stem leakage and media contamination. Achieving absolute leak-free operation for high-temperature steam and thermal oil.
Crafted with heat-resistant alloy materials (WC6, WC9, C12) and stainless steel, the valve withstands extreme high-temperature and high-pressure conditions (Class 150~1500 pressure rating). With stable performance in steam and thermal oil systems up to ultra-high temperatures.
Offering straight, angle and throttle structural types, the valve adapts to different industrial pipeline layouts and flow control needs. Throttle type for precise flow adjustment, angle type for space-saving installation in vertical pipelines.
The bellows construction reduces wear on the valve stem and sealing components, minimizing the need for regular maintenance and replacement. The high-grade material selection and plasma welding technology further extend the valve’s service life in demanding industrial environments.
The precision-machined valve seat and disc enable smooth, accurate flow control of high-temperature steam and thermal oil, avoiding sudden flow changes that could damage industrial equipment. ssential for power generation and chemical processing systems.

This High Temperature Steam Thermal Oil Manual Bellows Stop Valve is specially designed for industrial sectors with high-temperature and high-pressure fluid control demands, and is widely used in:
Power Generation: Controls steam and thermal oil flow in thermal power plants, nuclear power plant auxiliary systems and biomass power plants, with leak-proof design to ensure safe and continuous power generation.
Chemical Processing: Manages high-temperature, corrosive chemical media and thermal oil in chemical reactors, distillation columns and heat exchange systems, preventing media leakage and equipment corrosion.
Oil and Gas: Regulates high-temperature steam flow for crude oil refining and gas processing, with high-pressure resistance for refinery pipeline systems.
Water Treatment: Handles high-temperature hot water and steam flow in industrial water treatment systems, with bellows sealing to prevent heat loss and water contamination.
Pulp & Paper: Controls thermal oil and chemical fluid flow in paper mill drying and processing lines, adapting to the high-temperature working environment of pulp production.
The metal bellows fully isolates the valve stem from the internal high-temperature fluid, eliminating stem leakage—the most common issue of traditional stop valves in high-temperature systems. This design also prevents external contaminants from entering the valve and contaminating the media, ensuring pure fluid flow for critical industrial processes.
Yes, the valve is exclusively engineered for both high-temperature steam and thermal oil systems. Its heat-resistant alloy materials and bellows sealing design are optimized for the physical and chemical properties of these two media, with stable performance and leak-free operation for both applications.
