Description
RAINLING - Reliable Control 3/4’ Solenoid Valve RL-EVA75
RAINLING's solenoid valve is designed to meet the demands of modern irrigation systems with a focus on durability, flexibility, and precise control. Engineered for both residential and commercial use, it ensures consistent water regulation even in harsh conditions.
Manual Flow Adjustment
Integrated flow control knob allows easy manual adjustment:
- Turn clockwise to reduce flow, counterclockwise to increase.
- Supports full manual shut-off of the valve.
Manual Override Switch
- When the switch is vertical, the valve is open and solenoid control is bypassed.
- When horizontal, the valve is closed and solenoid control is enabled — ideal for system testing or maintenance.
Highly Durable Construction
- Valve body made of nylon reinforced with glass fiber, offering high strength and resistance to external impacts and pressure.
- Diaphragm made from EPDM rubber, known for its excellent resistance to heat, chemicals, and aging.
- Withstands fluid temperatures up to 60°C, ensuring stable operation in most irrigation environments.
- Excellent resistance to chemical corrosion and cavitation, extending product lifespan.
Smooth Operation & Water Hammer Protection
Gradual opening and closing mechanism prevents system damage due to sudden pressure changes.
Controller Compatibility
Compatible with a wide range of irrigation controllers for residential, landscape, and garden use.
100% Factory Water Testing
Each valve is individually tested to ensure leak-free and reliable performance.
Warranty & Support
Backed by a 3-year warranty, ensuring long-term peace of mind.

Frequently Asked Questions
What materials are used in the construction of the RL-EVA75 solenoid valve?
The valve body is constructed from high-strength, glass fiber-reinforced nylon, and the diaphragm is made of EPDM rubber, providing excellent resistance to heat, aging, chemical corrosion, and cavitation.
How does the manual override switch function?
The manual override switch features two modes: when positioned vertically, the valve is open and bypasses solenoid control; when positioned horizontally, the valve is closed and solenoid control is enabled. This is ideal for system testing and maintenance.
What is the operating pressure range and maximum fluid temperature for this valve?
The valve operates within a pressure range of 0.5 to 8 Bar and can withstand fluid temperatures up to 60°C.
What are the electrical specifications for the solenoid?
The valve operates on a drive voltage of AC24V (±10%) at 50/60Hz, with an opening current of 0.3A and a holding current of 0.18A.
How does the valve protect the irrigation system from water hammer?
It features a gradual, smooth opening and closing mechanism designed to prevent sudden pressure changes that can cause water hammer and damage system components.
What quality assurance and warranty are provided?
Every single valve is 100% water pressure tested at the factory before shipment. The product is backed by a 3-year warranty for long-term reliability and peace of mind.
