U.S. Solid 1/2″ Stainless Steel Solenoid Valve
This normally closed valve operates at DC 24V ±10% and features a 1 inch NPT threaded connection. Its pressure range spans 0.1–10 bar, and it handles temperatures from -30 to 150°C, making it suitable for diverse applications such as water supply, air lines, and diesel flow control. The valve uses industrial-grade stainless steel and a Viton seal for durability and chemical resistance, ensuring stable operation with minimal leakage or fluctuations in flow. Its precise mechanism enables accurate control of flow rates, contributing to dependable automation outcomes.
U.S. Solid 1/8″ High Temp Solenoid Valve
Designed for high-temperature clean media pipelines, this direct-acting valve withstands up to 572°F (300°C) and uses 304 stainless steel with PEEK/PTFE seals for corrosion resistance. It starts from zero pressure, requiring no pilot pressure to operate, which supports instant on/off automation. The combination of stainless steel body and low-friction seals provides long-term reliability in challenging environments, including steam and hot water lines. Its robust construction helps prevent valve deformation and leakage under elevated temperatures.
U.S. Solid 3/4″ Stainless Steel Solenoid Valve
With a 0.1–10 bar operating range and -30 to 150°C temperature tolerance, this 24V AC normally closed valve uses stainless steel and Viton sealing for durability and chemical resistance. The design emphasizes precise, reliable control of flow, delivering accurate flow rates with minimal fluctuations. It’s suited for high-pressure or high-temperature applications across water, air, and diesel systems, offering robust performance under demanding conditions.
SNS AC110V 1/4″ NPT High Temperature Brass Valve
Brass body with 1/4″ NPT port and AC110V operation, this high-temperature valve targets water, air, and oil applications. It is designed to endure temperatures from -5 to 180°C, making it suitable for demanding environments. The valve features O-ring seals and reliable normally closed operation, ensuring safe shutoff when power is removed. Its robust build supports stable performance with frequent cycling in industrial settings.
U.S. Solid 1/4″ Brass Electric Solenoid Valve 24VDC
This brass-bodied solenoid valve is corrosion resistant and suited for high-temperature projects. It uses a Viton seal for resistance to heat and chemicals, with a fast response time—opening or closing in under a second when energized or de-energized. The valve is designed for durability, with a lifecycle exceeding a million cycles under proper operating conditions, making it suitable for long-term automation systems involving fuels or cleaners beyond drinking water.
High Temperature Brass Solenoid Valve 1/2″ NPT AC110V
Engineered for extreme environments, this 1/2″ NPT valve operates on AC110V with a 145 PSI working pressure. It employs a brass body, premium coil, and Teflon gasket, delivering fast, millisecond response and a normally closed design for safety. It is built for tens of thousands of cycles and is suitable for steam, water, and oil control, particularly where high temperatures are involved.
Buying Guide
Key purchase considerations help ensure you select a valve that fits your system requirements and delivers reliable operation over time.
- Material and seals: Stainless steel bodies with Viton seals offer high chemical and temperature resistance, while brass bodies are robust and weld-friendly but may be unsuitable for drinking water in some cases.
- Temperature and pressure ratings: Match the valve’s temperature range and pressure rating to your media and operating conditions. High-temperature media require valves rated well above ambient temperatures to avoid deformation and leaks.
- Actuation type and voltage: DC and AC actuation support different control strategies. Direct-acting valves start at zero pressure and respond quickly, while pilot-operated models can handle higher flow with different control schemes.
- Port size and connection: Port size (NPT, 1/4″, 1/2″, 3/4″) and thread type affect compatibility with existing piping. Ensure the enclosure and installation space accommodate the valve’s dimensions.
- Media compatibility: Check compatibility with water, air, diesel, oil, steam, or corrosive chemicals. Seals and gasket materials influence chemical resistance and longevity.
- Durability and lifecycle: Look for valves designed for millions of cycles if frequent cycling is expected. Durable construction reduces maintenance and downtime.
- Safety features: Normally closed configurations provide fail-safe shutdown when power is lost. Consider emergency shutoff requirements in your system design.
- Certification and warranties: Manufacturer warranties and certifications may impact long-term reliability and compliance with industry standards.
In summary, high-temperature solenoid valves come in various configurations to suit different systems. Consider media compatibility, temperature tolerance, actuation method, and mechanical fit to ensure dependable performance and safe operation in demanding environments.
