Product Description:
The H3S Series is a 2/2-way normally closed piston pilot-operated solenoid valve, specifically designed for high-pressure fluid control applications reaching up to 360 bar (5,200 PSI). This valve is engineered to provide dependable ON/OFF control for various media, including water, air, gas, oil, and other neutral fluids, ensuring outstanding performance even in challenging high-pressure settings.
Featuring a piston pilot-operated mechanism, the H3S Series requires a minimum differential pressure of 1 bar to function effectively. This characteristic makes it an ideal choice for medium to large diameter piping systems that demand high flow capacities. The robust construction includes a stainless steel body combined with advanced sealing materials such as PTFE and PEEK, which contribute to the valve's exceptional durability, corrosion resistance, and leak-tight operation under severe pressure conditions.
Available in port sizes from 1/4″ up to 1″ and with orifice diameters ranging between 10mm and 25mm, the H3S Series offers superior flow capabilities, featuring Cv values as high as 10.0. Produced in Ningbo, China, this valve is recognized globally for its quality and reliability in managing high-pressure systems across various industries.
Features:
High-Pressure Capability
This product is designed to withstand demanding high-pressure applications with a maximum working pressure reaching up to 360 bar (5,200 PSI). For larger sizes featuring AC operation, the maximum pressure is rated at 300 bar, ensuring robust performance in intense environments.
Piston Pilot Operated Design
Utilizing a pressure-assisted piston pilot design, the valve guarantees reliable switching with a minimum differential pressure requirement of just 1 bar. This feature ensures consistent and efficient operation under varying pressure conditions.
2/2 Way Normally Closed Function
Equipped with a spring-return mechanism, the valve remains closed when de-energized. This fail-safe design provides enhanced safety by preventing unintended flow in the event of power loss.
Stainless Steel Body
Constructed from premium stainless steel, the valve body offers exceptional resistance to corrosion and maintains structural integrity. This makes it ideal for long-term use in harsh and challenging environments.
Advanced Seal Materials
The use of advanced seal materials such as PTFE and PEEK ensures superior leak-tight performance. These seals provide excellent chemical resistance and maintain durability under extreme pressures and temperature conditions.
High Flow Capacity
Featuring large orifice sizes ranging from 10mm to 25mm, the valve achieves outstanding flow coefficients (Cv) between 1.8 and 10.0. This high flow capacity allows for maximum throughput in demanding applications.
Wide Port Size Range
The valve is available with port sizes from 1/4″ up to 1″, providing flexible options for seamless integration into various system configurations.
Wide Voltage Options
Compatible with multiple voltage inputs including 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC (50/60Hz), this valve can easily meet the requirements of diverse control systems.
High Production Capacity
With an annual production capacity of 500,000 units and a monthly output of 10,000 pieces, this product ensures a reliable supply, efficiently fulfilling large-scale orders without delay.
