WJIAAA 1/4" Water Flow Control Valve, RO Filter System Adjustable 2-Way Needle Valve with Base, POM Plastic Pressure Reducer and Flow Regulator for Water Purifier Machine Dispenser

["Precise Flow Control with 1/4-inch Needle Valve: This water flow control valve features a 2-point (6.4mm/1/4\") pipe diameter and a needle valve design for water flow regulation. Its bidirectional structure is intended for diverse installation needs. Designed for use with RO filter systems, drinking water dispensers, aquarium systems, and small water purifiers using 2-point PE tubing.","Durable Copper and POM Material Construction: The main body is made of POM plastic, designed to meet drinking water standards and intended for applications involving water contact. The adjustment knob and lock nut are copper, selected for material strength and anti-rust properties. This POM plastic pressure reducer is suitable for repeated adjustment in water system applications.","Quick-Connect Design with Tool-Free Installation: This POM flow control valve uses 2-point quick-connect fittings at both ends—insert to lock, press to release. No additional tools are required for installation or maintenance. An integrated mounting base allows for direct screw mounting to walls or equipment, designed to help reduce pipe movement. Works as a hose meter regulator for various water systems.","Temperature and Pressure Specifications with Easy Operation: As an adjustable waterflow speed controller connector fitting, this unit is designed for operation with 0-50°C water within standard household water pressure ranges. The knurled knob features a non-slip design: clockwise rotation reduces flow, counter-clockwise rotation increases flow. The sealing components are intended for use in RO filter systems requiring flow regulation.","Sealing Features and Compact Dimensions: The quick-connect port includes a sealing ring with a copper locking structure. Dimensions are 47×37×14mm. This 1/4\" water flow control regulator and pressure reducer is sized for installation inside cabinets or tight spaces. Designed for use as a hose meter regulator for reverse osmosis units or water dispensers."]
