制冷電磁閥，F(xiàn)DF-19

產(chǎn)品概述

FDF-19制冷電磁閥是一種專為制冷系統(tǒng)設(shè)計(jì)的常閉型電動(dòng)閥門，適用于控制氟利昂制冷劑（如F12、F22、F502）、水、氣體及高溫蒸氣等介質(zhì)的通斷。該產(chǎn)品通過(guò)電信號(hào)實(shí)現(xiàn)遠(yuǎn)程自動(dòng)化控制，廣泛應(yīng)用于冷凍機(jī)械、空調(diào)裝置、化工設(shè)備、食品加工及紡織機(jī)械等領(lǐng)域，能有效調(diào)節(jié)管路中介質(zhì)的流動(dòng)方向或切斷流量。其設(shè)計(jì)兼顧性能穩(wěn)定性與操作便捷性，適合在-40℃至+105℃的介質(zhì)溫度范圍內(nèi)工作。128

結(jié)構(gòu)特點(diǎn)

FDF-19采用黃銅閥體與進(jìn)口耐腐蝕膜片材料，確保長(zhǎng)期使用的密封性和耐用性。電磁線圈采用全封塑工藝，具備優(yōu)異的絕緣、防水及抗振性能。閥門結(jié)構(gòu)緊湊，安裝方式靈活，支持銅管喇叭口連接（接管尺寸φ22×1.5mm），垂直安裝時(shí)線圈朝上以優(yōu)化性能。主閥采用導(dǎo)閥式（伺服式）結(jié)構(gòu)，通電時(shí)通過(guò)磁場(chǎng)驅(qū)動(dòng)導(dǎo)閥芯形成壓差，推動(dòng)主閥快速開啟；斷電時(shí)通過(guò)彈簧復(fù)位關(guān)閉，響應(yīng)迅速且能耗低。1614

• 流量特性：Kv值（水）為4.5m³/h，滿足中等流量需求。2817

應(yīng)用場(chǎng)景

FDF-19適用于制冷系統(tǒng)的液管路、吸氣管路及熱氣旁通管路，可集成于冷庫(kù)、中央空調(diào)、熱泵機(jī)組等設(shè)備中。其穩(wěn)定性和快速啟閉特性使其在需要精確控溫或頻繁切換的工業(yè)場(chǎng)景中表現(xiàn)優(yōu)異，如食品冷凍生產(chǎn)線、醫(yī)藥冷鏈倉(cāng)儲(chǔ)等。安裝時(shí)需保持管道清潔，建議前置過(guò)濾器以避免雜質(zhì)堵塞。51019

Product Overview

The FDF-19 refrigeration solenoid valve is a normally closed electric valve designed for refrigeration systems, suitable for controlling the flow or shut-off of refrigerants (e.g., F12, F22, F502), water, gases, and high-temperature steam. It enables remote automation via electrical signals and is widely used in freezing equipment, HVAC systems, chemical plants, and food processing. Its operational temperature range covers -40℃ to +105℃, ensuring reliability in diverse environments.1814

Design Features

The valve body is constructed from brass with corrosion-resistant diaphragms, while the fully encapsulated coil provides insulation, water resistance, and vibration resistance. Its compact design supports vertical installation (coil upward) with φ22×1.5mm flare tube connections. The servo-assisted mechanism ensures fast response: energizing the coil opens the pilot valve to create pressure differentials for main valve activation, while de-energizing resets the valve via spring force. This design balances efficiency with low energy consumption.61725

Technical Specifications

• Pressure Range: 0.03~2.1MPa (gas), 0.03~1.7MPa (liquid).
• Voltage Options: AC 24V-380V or DC 12V-220V.
• Media Compatibility: Compatible with refrigerants, air, water, and oils (<4°E viscosity).
• Environmental Limits: Operates at ≤50℃ ambient temperature and ≤85% humidity.
• Flow Capacity: Kv value of 4.5m³/h (water).2819

Applications

Ideal for liquid lines, suction lines, and hot gas bypass in refrigeration systems, the FDF-19 is commonly integrated into cold storage units, central air conditioning, and heat pumps. Its precision control suits industrial applications requiring temperature stability, such as frozen food production or pharmaceutical storage. Installation requires clean pipelines and a recommended upstream filter.51025
