Solar electric butterfly valve specially designed forMedia transport and flow control of solar thermal/photovoltaic systemsDesigned to adapt to outdoor environments with large temperature fluctuations and media mostly composed of water/thermal oil, it has become a key control component of solar energy systems due to its weather resistance, corrosion resistance, and intelligent controllability. Its specific applications are as follows:
Suitable media: tap water, circulating hot water (≤ 120 ℃), antifreeze type heat transfer fluid
Specific scenario:
Household solar water heater: water tank inlet/outlet control, circulation pipeline flow regulation
Commercial centralized hot water projects (hotels, hospitals, schools): circulation loop between collectors and hot water storage tanks, and switching of hot water delivery pipelines
Core requirements: Temperature resistance (suitable for hot water circulation), corrosion resistance (to avoid water quality corroding the valve body), intelligent linkage (can be connected to a temperature controller, automatic start stop)
Suitable media: photovoltaic panel cooling circulating water, inverter cooling fluid, thermal conductivity medium for energy storage system
Specific scenario:
Large scale ground photovoltaic power station: control of photovoltaic array cooling circuit, flow regulation of energy storage battery cooling system
Distributed photovoltaic power station: cooling circulation pipeline for rooftop photovoltaic panels, cooling medium transportation for grid connected cabinets
Core requirements: Weather resistance (outdoor high/low temperature), UV resistance (to avoid valve body aging), low power consumption (compatible with photovoltaic power supply), anti scaling (to ensure cooling efficiency)
Suitable media: High temperature hot water (≤ 95 ℃), heating circulating water, antifreeze heat transfer oil
Specific scenario:
Rural solar heating project: circulation control of collectors and radiators/underfloor heating pipelines
Centralized solar heating station: flow regulation of heating main pipe, switching of zone heating
Core requirements: Low temperature resistance (no freezing or cracking below 20 ℃ outdoors in winter), tight sealing (to avoid heat loss), intelligent regulation (automatic flow control based on room temperature)
Suitable media: industrial hot water, thermal oil (≤ 200 ℃), process circulating water
Specific scenario:
Industrial waste heat recovery+solar complementary system: process pipeline medium transportation control
Solar drying system (agricultural products, medicinal materials): adjustment of hot air circulation pipeline
Solar seawater desalination system: desalination water transportation, raw water pretreatment pipeline switching
Core requirements: high temperature resistance (suitable for industrial grade medium temperature), corrosion resistance (some scenarios contain salt/mild chemical media), pressure resistance (high pressure scenarios in industrial pipelines)
Solar powered swimming pool heating system: pool water circulation heating control, constant temperature regulation
Solar water treatment system: opening and closing of water reuse pipelines, flow control
Agricultural solar irrigation system: irrigation water transportation, zoning irrigation switching (resistant to outdoor humid environments)
The core advantage of solar electric butterfly valves isAdapt to the special working conditions of solar energy systemsDifferent from general electric butterfly valves, it focuses on meeting the following requirements:
Environmental adaptation: UV resistance, high and low temperature resistance (-40 ℃~200 ℃), and resistance to outdoor aging (the valve body is mostly made of 304/316 stainless steel or anti-corrosion coating);
Medium adaptation: Suitable for commonly used solar media such as water, thermal oil, antifreeze, etc., to prevent scaling and corrosion;
Functional adaptation: Low power design (can be directly connected to solar panels for power supply), supports intelligent linkage (interfaces with temperature controllers, PLCs, and IoT systems to achieve remote/automatic control);
Scenario adaptation: Accurate flow regulation (ensuring solar heat collection/exchange efficiency), stable sealing performance (avoiding system failure caused by medium leakage).
