Why Choose HP Valves for Your Operation

HP Valves has built its reputation on a simple principle: deliver flow control solutions that outlast and outperform in critical service environments. Their product line includes pressure seal gate valve, globe valve, and check valve configurations designed specifically for high-energy piping systems where failure is not an option.

What sets HP Valves apart is their commitment to maintainability. Rather than requiring full device replacement during outages, their valves are designed for efficient in-line maintenance, reducing turnaround time and total cost of ownership. Forged bodies with uniform wall thickness provide superior resistance to thermal cycling, while optimized trim designs extend valve stem and seat life across numerous operating cycles. HP Valves uses finite element analysis (FEA) to evaluate performance under cold-, warm-, and hot-start conditions, applying those insights to deliver significantly extended valve lifetimes suited for modern cycling power plants.

Each valve is built using the latest material standards, including stainless steel alloys and high-chrome configurations suited for aggressive process medium conditions. Whether managing superheated steam, high-pressure condensate, or flashing drain lines, HP Valves deliver the performance that critical systems demand. All products are developed in accordance with the highest standards for safety and quality, with factories certified to ISO 9001, ISO 14001, and PED standards.

HP Valve Capabilities and Product Range

HP Valves manufactures a comprehensive range of products to address both isolation and control requirements across a variety of specific application needs:

Isolation Valves: Pressure seal gate valve and globe valve solutions engineered for high-pressure, high-temperature on-off service. The full range includes gate valves, globe valves, check valves, ball valve configurations, blowdown valves, strainers, and non-return valves. These include main steam isolation valve configurations rated for cycling power plant operations, ensuring tight shutoff and long-term leakage prevention even under severe thermal stress.

Control Valves: Purpose-built control valve products designed to manage flashing, cavitation, and critical pressure drop conditions. The range includes feedwater valves, condensate valves, spraywater valves, choke valves, and pressure reduction valves. Every control valve is engineered to order for the specific application, with features like noise reduction, rangeability, and high shutoff class performance. 

Steam Conditioning Valves: With over 100 years of experience in steam conditioning systems developed in Sweden, HP Valves is a world-leading supplier of complete turbine bypass systems and attemperator systems designed to protect downstream equipment and maintain safe operating parameters. The product range includes turbine and process bypass valves, pressure reduction valves, stop valves, desuperheaters (ring-style, probe style), attemperators (ring-style, floating liner), feedwater heater bypass valves, and spray water atomizing nozzles.

HP Valves also offers a new Severe Service Flashing Drain Valve (SSFD) featuring a quick-change seat for improved wear protection and a robust sealing system optimized for demanding drain line installation requirements.

OEM Spare Parts & Tools: HP Valves offers genuine spare parts and tools for their complete range of products, including upgrade trims for valves in operation. Valve consumables, replacement and upgrade parts, and seat-cutting tools are available with short delivery times. It is recommended to use OEM parts to guarantee proper performance of each component after installation.
