1/2" Valves

1/2" Normally Open Plastic Solenoid Valves

Key Features & Benefits

  • Robust Construction: Made from engineered nylon plastic (PA66), these valves are corrosion-resistant, lead-free, and ideal for potable and food-grade applications.
  • Zero Differential Design: Offers consistent, accurate flow control—allowing media to pass freely when unpowered and stopping flow instantly when energized, eliminating performance issues common with standard valves.
  • Durable Components: Stainless steel internals and an EPDM diaphragm provide enhanced reliability and a wider operating temperature range.
  • Versatile Voltage Options: Available in multiple voltages (12V DC, 24V DC, 24V AC, 110V AC, and 220V AC) to suit various power supplies.
  • Fast Response & Weatherproof: With a response time of less than one second and an H Class – IP65 – NEMA 4 rating, these valves perform reliably in both indoor and outdoor environments.

Common Applications

Our 1/2” normally open plastic solenoid valve is ideal for a variety of applications. In residential and commercial water systems, it offers efficient control for irrigation and plumbing. Industrial applications benefit from its use in process automation, HVAC systems, and chemical dosing. Its fast-acting operation makes it suitable for regulating air and gas flows, while its robust construction ensures dependable performance in both controlled and harsh environments.

How to Choose the Right 1/2" Normally Open Plastic Solenoid Valve

When selecting a valve, consider your system’s specific needs:

  • Pressure and Flow Rate: Ensure the valve's 0-90 PSI pressure range and Cv 4.8 flow rate are adequate for your system's demands
  • Material & Media Compatibility: Verify that the EPDM seals and PA66 plastic body are compatible with the media you will be controlling. Always consult chemical compatibility charts or experts, especially for fluids beyond water, air, or gas
  • Voltage & Installation Environment: Choose from a range of voltage options and note the valve’s weatherproof rating (H Class – IP65 – NEMA 4) for outdoor or harsh settings.
  • Operation Mode: Confirm that a normally open valve configuration aligns with your system's fail-safe and operational requirements - remembering it defaults to OPEN and closes when powered.

FAQs

Q: What is the operating temperature range for these valves?
A: The valve operates effectively between 15°F and 175°F, with the EPDM seal offering enhanced tolerance in some applications.

Q: Can this valve handle various media?
A: Yes, it is suitable for water, air, gas, and similar fluids. Always verify compatibility for specific chemicals.

Q: How fast does the valve actuate?
A: These plastic valves have a response time of under one second for rapid and reliable control.

Q: What does "zero differential pressure" mean for this valve?

A: "Zero differential" signifies that this valve operates reliably even when there is little to no pressure difference between the inlet and outlet ports. This makes it ideal for gravity-fed systems or applications with very low pressure.

Q: Can I use this valve outdoors?

A: Yes, these valves are designed for both indoor and outdoor use. They feature a coil with an IP65 and NEMA 4 rating, providing robust protection against dust, rain, and splashing water.
