Product Description:
The H4S Series represents a 2/2-way normally closed direct-acting solenoid valve, specifically designed for ultra-high pressure fluid control tasks reaching up to 700 bar (10,000 PSI). It is engineered to provide reliable ON/OFF switching capabilities for various media including air, water, gas, and other neutral fluids.
This valve excels in delivering outstanding performance even in the most demanding high-pressure environments. Its direct-acting mechanism guarantees dependable operation starting from zero differential pressure, making it particularly suitable for applications that require precise control across the entire pressure range.
Constructed with a robust Stainless Steel 316 body, the H4S Series valve incorporates advanced sealing materials such as PEEK and PCTFE. These features ensure exceptional durability, resistance to corrosion, and leak-tight performance under extreme pressure conditions.
Available with port sizes of 1/8″ and 1/4″ and equipped with a 0.5mm orifice, this valve allows for accurate flow control highlighted by a Cv value of 0.02. Manufactured in Ningbo, China, the H4S Series is recognized worldwide for its high quality and reliability in ultra-high pressure systems.
Features:
The valve boasts an ultra-high pressure capability, with a maximum working pressure reaching up to 700 bar (10,000 PSI). This makes it ideal for use in demanding high-pressure applications where reliability and durability are critical.
Featuring a direct acting operation, the valve utilizes a spring-return mechanism that enables functionality even at zero differential pressure (0 bar). This design ensures consistent and dependable performance throughout the entire pressure range.
Its 2/2 way normally closed function is maintained by the spring-return system, which keeps the valve securely closed when de-energized. This fail-safe operation enhances safety and prevents unintended fluid flow.
Constructed from premium stainless steel 316, the valve body delivers exceptional corrosion resistance and structural strength. This robust material choice supports long-term service in harsh and corrosive environments.
The incorporation of advanced seal materials such as PEEK and PCTFE ensures superior leak-tightness and excellent chemical resistance. These seals perform reliably under extreme pressure and temperature conditions.
With a precise flow control capability, the valve features a 0.5mm orifice size and a Cv value of 0.02, enabling accurate and repeatable regulation of fluid flow.
Designed with compactness in mind, the valve is available in 1/8″ and 1/4″ port sizes, making it suitable for installations where space is limited.
The valve supports a wide range of voltage options, including 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC (50/60Hz), allowing compatibility with various control systems.
Backed by a high production capacity of 500,000 units annually and 20,000 units monthly, the manufacturer ensures a reliable supply to meet bulk order demands.
