VR2-4M Vibration Sensor

Overview

The VR2-4M is a widely used solenoid valve designed for precise fluid control in industrial and commercial systems. Its robust construction and reliable performance make it a preferred choice for engineers and technicians. The valve operates by converting electrical energy into mechanical motion, enabling rapid opening or closing of fluid pathways. Suitable for both liquid and gas applications, the VR2-4M is engineered to withstand high pressures and harsh environments. Its modular design allows for easy integration into existing systems, reducing installation time and maintenance costs.

The VR2-4M consists of a solenoid coil, plunger, valve body, and sealing components. When an electrical current is applied, the coil generates a magnetic field that moves the plunger, opening or closing the valve orifice. This action controls the flow of fluid with minimal lag time. The valve body is typically made of brass for corrosion resistance, while internal parts may use stainless steel for durability. Seals are often composed of nitrile or fluorocarbon rubber to ensure compatibility with a wide range of fluids. The VR2-4M's design prioritizes efficiency, with low power consumption and high flow rates.

Key Features

The VR2-4M stands out for its compact size, which allows installation in space-constrained environments. Its fast response time—often under 50 milliseconds—ensures precise control in dynamic systems. The valve is also designed for low noise operation, reducing workplace disturbances. Additional features include a wide operating temperature range (-10°C to 80°C) and compatibility with voltages ranging from 12V DC to 220V AC. These attributes make the VR2-4M adaptable to diverse industrial settings, from water treatment plants to automated manufacturing lines.

Application Areas

The VR2-4M is commonly deployed in water treatment systems for controlling chemical dosing and filtration processes. In HVAC applications, it regulates refrigerant and water flow in chillers and heat pumps. The valve also plays a critical role in industrial automation, where it manages pneumatic or hydraulic circuits. Other uses include irrigation systems, medical equipment, and beverage dispensing machines. Its versatility stems from its ability to handle various fluids, including water, oils, and mild chemicals, provided compatibility with seal materials is confirmed.

Maintenance and Precautions

Regular inspection of the VR2-4M is recommended to ensure optimal performance. Check for leaks, corrosion, or coil damage periodically. Clean the valve body if debris accumulation is observed, using only compatible cleaning agents to avoid seal degradation. When installing, ensure proper alignment and use thread sealant where applicable. Avoid exposing the solenoid coil to excessive moisture or heat, as this may reduce lifespan. Always disconnect power before performing maintenance to prevent electrical hazards.

B2B Procurement Guide

When sourcing VR2-4M valves, verify certifications such as ISO 9001 or CE marking to ensure quality standards. Bulk purchases typically offer cost savings, with discounts available for orders exceeding 50 units. Lead times vary by supplier but commonly range from 2–6 weeks. Consider working with distributors that provide technical support and warranty coverage. Request samples for testing compatibility with your specific application before large-scale procurement. Compare specifications carefully, as minor variations in pressure ratings or electrical requirements can impact performance.
