Valve and Controller for Dust Collector System

Product catalog summary

Overview: The document provides comprehensive technical specifications and operational principles for components used in dust collector systems, with a focus on diaphragm valves. These valves are crucial for pulse cleaning and filtering systems, ensuring efficient dust removal from fabric filters.

Features of Diaphragm Valves: Designed for fast response and large flow volume, diaphragm valves enhance the cleaning action on fabric filters. They consume low air and are compatible with programmable sequential controllers, allowing easy adjustment of jet pulse timing and duration.

Working Principle: Diaphragm valves operate with two air chambers separated by a diaphragm. When the pilot valve orifice opens, air in the upper chamber is exhausted quickly, causing the diaphragm to move and allow a burst of air into the lower chamber, inflating the fabric filter and shaking off dust. The diaphragm returns to its original position when the orifice closes, equalizing pressure in both chambers.

Applications: Suitable for various dust collector systems, including filter bags, barrels, flat bags, ceramic tubes, and metal fiber filters. They are designed for quick installation and easy maintenance, with fewer components and a compact design.

Electrical Features: Valves feature coil insulation of Class F, with electrical protection standards of IP65. They operate on standard voltages of 24Vdc, 110Vac, and 220Vac, with power consumption of 12W for DC and 17VA for AC.

General Features: Constructed from aluminum, with diaphragms made from NBR or specially designed plastics. They operate within a temperature range of -20 to 85°C for operation and -20 to 60°C for ambient conditions.

Order Information: Detailed order information includes connection sizes, power supply options, and diaphragm materials. Models are available with both female and outer thread connections, as well as integrated and remote types.

Specifications: The document outlines specifications for various models of controllers and devices used in industrial applications, including power supply requirements, adjustable ranges for intervals and spray times, fuse ratings, ambient temperature ranges, and dimensions for different models.

Pressure Differential Controller: Designed for dust collector systems, it operates by using the pressure difference between air intake and exhaust to control solenoid valves. Features include an LCD display, microprocessor control, remote control capability, and RS485 Modbus communication protocol.

Sequential Controller: Specifications include power supply, interval and spray time ranges, fuse ratings, and ambient temperature limits. It controls airing electro-magnetic valves using a microprocessor, with adjustable jetting time and interval settings.

Air Hammer and Pneumatic Vibrator: Specifications for air hammers and pneumatic vibrators include air consumption, impact weight, useful pressure, and frequency. These devices are used for applications such as cleaning pipes, tanks, and vibrating separators.

Capacitance Level Switch: Measures changes in capacitance to detect material levels in silos. Specifications include housing and probe materials, supply voltage, output rating, power consumption, and operating temperature.

Rotary Paddle Level Switch: Used to detect material levels in bins, it operates by stalling a rotating paddle when material is present, triggering a micro switch. Specifications include power consumption, contact rating, rotary speed, torque, and housing material.

General Features and Applications: Highlights features such as airtight sealing, adjustable torque, and stable performance for various devices. Applications include use in industries handling powders, chemicals, and other materials requiring precise control and measurement.

Vibrating Probe Level Switch: Similar to the tuning fork, this switch uses piezoelectric elements for reliable and maintenance-free operation. It is designed to withstand lateral loads and static electricity, with fail-safe features to prevent malfunctions due to power shortages.

RF Capacitance/Admittance Level Switch: Consists of a guard section, active section, grounding, and insulation. It is designed to overcome medium attachment and ensure signal accuracy, suitable for detecting various media without being affected by attachments.

Snifter Dust Monitor: Used for detecting filter bag breakage, this compact device can detect particles as small as 0.3 μm. It features automatic setup, two alarm relays, and a three-color LED for filter condition indication.

Global Network: FineTek has offices and factories in Taiwan, China, Singapore, the U.S., and Germany, providing a global network for distribution and support.

Valve and Controller for Dust Collector System-3

PRODUCT INFORMATION WORKING PRINCIPLE The diaphragm valves are used specifically in the dust collector system. The valve consists of 2 air chambers divided by a piece of diaphragm. The 2 chambers are connected through an air passage (air passage's diameter is smaller than the orifice of the pilot valve). When the orifice opens, the air in the upper chamber is exhausted much faster than the speed of air that enters through the air passage. The air pressure of the upper chamber drops significantly, the higher pressure of the lower chamber pushes the diaphragm up and opens a bigger passage for air...
