Pulse water electric valve

Types

These pulse water electric valves are automatic components that control water pressure in pipes, often used in irrigation systems, aquaculture, greenhouses, hydroponics, and other relevant areas.

Here are the main types of electric water valves in bulk that one can get from wholesalers:

• Pulse)

  The pulse electric valve is precise and designed for pulse solenoid control, with some internal kill cup or diaphragm, mostly used for air and fluid control.

• Timed electric water valve

  It is an automatic valve that opens and closes based on a pre-set time schedule, especially for irrigation systems, is useful in aqua farming and hydroponics, where precise water timing is vital.

• Two-way electric water valve

  A two-way electric valve controls water flow in one direction, one inlet and one outlet, easily turning on or off the water supply.

• Three-way electric water valves

  As the name implies, these valves have three ports and are useful for mixing or diverting water in hoses. Three electric water valve configurations include mixing (hot and cold water) and diverting (alternate between two water sources).

• Solenoid valve)

  Solenoids electric water valves are electromagnet devices that turn on and off water flow, usually with an inbuilt solenoid valve kit, but it's important to note that not all solenoid kits are electric valves.

Design & Function

Design

Electric pulse water valve design usually consists of the following parts:

• Body material: The electric pulse water valve body material includes brass, stainless steel, plastic, or nylon, which are corrosion-resistant and durable. The body material depends on the water system's pressure, temperature, and chemical environment.
• Coil: The coil is generally made of copper wire and insulated, generating a magnetic field when electricity passes through it. The coil is mounted on the solenoid body to enable functionality.
• Solenoid: An insulated wire is wrapped around a metal core to form the solenoid, creating magnetic fields when electricity is passed.
• Diaphragm: This flexible membrane separates valve chambers. It opens and closes the valve by moving with solenoid attraction. Diaphragms are made of rubber or other elastic materials.
• Spring: This returns the solenoid and keeps the valve closed with no pulse. Springs are usually made of stainless steel to improve their durability.
• Ports: These are the openings that allow water to enter and exit the valve, usually designed in varying sizes to accommodate different pipe diameters.

Function

Pulse electric valve functions include the following:

• Pressure control: These valves help maintain water system pressure by regulating water flow, preventing overpressure that might cause damage to the infrastructure.
• AUTOMATIC operation: The electric operation allows for automation, eliminating manual intervention. These valves are integrated into smart irrigation systems controlled by timers, sensors, and controllers.
• Pulsation: The valve creates a pulsing action by opening and closing water flow in quick succession, making it useful for applications like fertilizer injection in hydroponics, where precise timing is key to success.
• Remote control: These valves allow water flow to be controlled remotely via electronic signals, improving convenience and reliability over manual valve systems.
• Safety shut off: These valves automatically shut off water flow during electrical failure or signals, preventing backflow or leakage and improving system safety.

Scenarios

Electric pulse valves are mainly used in irrigation, aquaculture, greenhouses, hydroponics, and other relevant areas for precise water control.

Here are common scenarios for purchasing electric water valves:

• Agricultural irrigation systems

  Electric pulse valves automate irrigation, improving efficiency by precisely controlling water flow and timing. They help farmers conserve water and optimize crop growth by delivering the right amount of water at the right time.

• Aquaculture systems

  In aquaculture, electric valves control water exchange, nutrient delivery, and waste removal in fish and shrimp farming systems. They help maintain the right water quality and levels for healthy aquatic life.

• Greenhouse agricultural systems

  In greenhouses, valves maintain moisture levels in soil and air for crops. They enable precise water delivery to plants based on needs, resulting in better crop quality and yields.

• Hydroponic systems

  Hydroponics relies on electric pulse valves for nutrient solution delivery to plants. They help farmers control the growth rates of plants outside the soil by precisely mixing and feeding nutrient solutions to plants.

• Engineered sand filters

  These valves cause rapid changes in water flow through filter media, enhancing backwashing and improving filter performance in aquaculture systems.

• Irrigation systems for golf courses and parks

  They are widely used in these electric irrigation systems to maintain the health and aesthetics of lush turfgrass and other ornamental plants.

How To Choose

There are salient factors wholesalers should consider when selecting the right electric water valve:

Supply voltage

These valves operate with different voltage ranges, such as 12V, 24V, and 220V. Choose the electric water valves that match their clients' irrigation system voltage, although 24V and 12V are common for low-voltage commercial and residential systems.

Valve material

Electric water valve materials impact their applications. For example, brass and stainless steel electric water valves are meant for commercial clients, as they offer durability and corrosion resistance. Plastic valves are ideal for inexpensive DIY home projects.

Flow rate

Different electric water valves have various flow rates. Therefore, it is necessary to look at the flow rates of the electric water valves to ensure they match the irrigation system requirements. On the flip side, low flow rates lead to high water pressure.

Orifice size

The orifice size affects the flow rate and pressure drop across the valve. Larger orifice size valves are ideal for high-flow applications such as pulse valves in irrigation systems, while smaller orifices are suitable for low-flow.

Temperature and pressure ratings

These ratings are important considerations when choosing electric water valves. The pressure rating of the valve should meet or exceed the system pressure. At the same time, the temperature rating should be higher than the maximum temperature of the fluid or environment.

Q&A

Q1. Do electric water valves fail open or close?

Electric water valves normally fail closed in a de-energized position, meaning it stays closed when there is no power. However, safety concerns always determine whether a system requires a fail-open electric water valve.

Q2. How are pulse valves different from solenoid valves?

Solenoid water valves use electromagnetic coils to control water flow by simply opening and closing. On the other hand, pulse valves use short, quick strokes to create a pulsed flow. Solenoid valves are general-purpose applications.

Q3. What is the mechanical lifespan of pulse valves?

Pulse valves typically last at least 500,000 cycles when properly maintained and installed under good conditions. Factors such as operating pressure, temperature, and media type affect the lifespan of these valves.

Q4. What devices are needed to manage electric water valves in irrigation systems?

These electric water valves can be managed by controllers or timers, which send electrical signals to the valves based on predetermined irrigation schedules or real-time environmental data from sensors.

Q5. Are pulse valves suitable for all fluids?

These valves are mainly designed for clean, low-viscosity fluids. While some pulse valves handle slurries or fluids with small solid particles, choosing a valve specifically designed for these fluids is good practice.
