Runxin auto control valve

Multiport Control Valve is a critical component used in water treatment systems, particularly in filters and softeners, to direct water flow through different cycles (e.g., filtration, backwash, rinse, regeneration).

1). Multiport Control Valve in Sand Filters / Media Filters
Function: Controls the flow of water through different filter cycles:
⦁ Filtration → Water passes through the media (sand, anthracite, etc.) to remove impurities.
⦁ Backwash → Reverses flow to flush out trapped debris. oRinse → Resettles the media after backwashing.
Common Applications: Pool filters, industrial water treatment, and irrigation systems.

2). Softener Valve (Specific to Ion Exchange Systems)
Function: Controls the flow of water through different softener cycles:
⦁ Filtration → Water passes through the softener resin to perform ion exchange, removing hardness minerals (e.g., calcium, magnesium).
⦁ Backwash → Reverses flow to flush out accumulated debris and suspended particles.
⦁ Rinse → Resettles the resin bed after backwashing to prepare for regeneration.
⦁ Regeneration → Restores resin effectiveness by flushing with a salt (brine) solution.
Common Applications: Residential and commercial water softening, industrial water treatment systems, and pre-treatment for RO systems.
Types: ⦁ Upflow vs. Downflow → Regeneration direction (bottom-to-top vs. top-to-bottom).
⦁ Metered vs. Timed → Triggers regeneration by actual water usage or preset schedule.

Key Takeaway
⦁ Filter valves = Physical filtration (backwash only, no chemicals).
Softener valves = Chemical ion exchange (requires salt regeneration).
Some advanced valves (e.g., Fleck 9100) can be configured for both roles, but media and cycles must match the application. Need help selecting one? Specify your water problem (e.g., hardness, iron, turbidity), and I’ll suggest the right valve type!

1). Primary Function

Filter Valve
Removes suspended solids (dirt, silt, sand, rust).

Used in sediment filters, multimedia filters (sand, anthracite), or carbon filters.
Softener Valve
Removes dissolved hardness ions (calcium, magnesium) via ion exchange.

Used exclusively in ion exchange water softeners.

2). Regeneration Process

Filter Valve
Backwash cycle: Reverses water flow to flush out trapped debris (no chemicals).

Rinse cycle only (no chemical injection).

Example: Pool sand filters, iron filters.
Softener Valve
Brine cycle: Uses saltwater (NaCl/KCl) to recharge resin beads by swapping hardness ions for sodium/potassium.

Includes brine draw, slow/fast rinse, and refill cycles.

Example: Residential/commercial water softeners.

3). Media Type

Filter Valve
Holds inert media like sand, gravel, activated carbon, or KDF.

Media traps particles physically.
Softener Valve
Contains cation exchange resin beads (polystyrene coated with Na⁺/K⁺ ions).

Resin chemically exchanges ions (Ca²⁺/Mg²⁺ → Na⁺).

4). Valve Design & Cycles

Filter Valve
Standard cycles: Service, Backwash, Rinse, Bypass.

No salt tank connection.

Often manual or timer-based backwash.
Softener Valve
Additional cycles: Brine Draw, Slow Rinse, Brine Refill.

Requires a brine tank for salt solution.

Typically metered (volume-based) or timed regeneration.

Why Multiport Valves Matter

1 -
Efficiency
Automates complex cycles without manual intervention.
2 -
Durability
Engineered for high flow rates and pressure resistance.
3 -
Customization
Some models allow programmable cycles for specific water conditions.

Multi-cartridge Filter Housing stainless steel micron filter for water purification

Cartridge filter housing is a critical component in liquid filtration systems, designed to securely hold and protect filter cartridges while allowing liquids to flow through the filter media. These housings are essential for industries that require reliable filtration solutions to remove contaminants from liquids, such as water treatment, pharmaceuticals, food and beverage processing, chemicals, and industrial applications.

 

Cartridge filter housings are typically constructed from durable materials like stainless steel, polypropylene, or fiber glass, providing excellent resistance to corrosion and ensuring long-term performance. They are available in a variety of configurations, including single or multi-cartridge designs, to accommodate different flow rates and filtration needs. These housings are engineered to securely seal the filter cartridges, preventing any bypass of unfiltered liquid, ensuring the integrity of the filtration process.

 

Designed for easy maintenance, cartridge filter housings offer the flexibility to replace or clean filter cartridges quickly, making them a convenient solution for systems requiring regular maintenance. Their efficiency and versatility make them ideal for applications where precise filtration is crucial for improving the quality of liquids, whether for industrial processes, potable water production, or high-purity applications.

UV Water Sterilizer – Advanced Ultraviolet Disinfection for Safe and Clean Water

UV Water Sterilizer Systems are advanced water purification devices that utilize ultraviolet (UV) light to eliminate harmful microorganisms such as bacteria, viruses, and protozoa from water. These systems are highly effective, environmentally friendly, and do not require the use of chemicals, making them a popular choice for both residential and commercial applications. UV sterilizers are often used in conjunction with other filtration methods, such as reverse osmosis or carbon filters, to ensure comprehensive water treatment. They are easy to install, require minimal maintenance, and provide a reliable method for ensuring safe and clean drinking water.

Multi-Layer Media Filter (Anthracite & Sand) for Iron & Sediment Removal

Multi-Media Filter (MMF)

Our Multi-Media Filter (MMF) is a highly efficient water filtration system designed to remove suspended solids, turbidity, and other impurities from water. Unlike single-media filters, MMFs use multiple layers of filtration media—such as sand, anthracite, and gravel—each with varying sizes and densities.

This layered structure allows for superior filtration, increased dirt-holding capacity, and longer operational cycles.

Multi-Media Filters are widely used in industrial, municipal, and commercial water treatment applications, serving as a crucial pre-treatment step for processes like reverse osmosis (RO) and ultrafiltration (UF). By ensuring cleaner water and reducing maintenance needs, MMFs enhance the overall efficiency of water treatment systems.
