Good Sealing Performance Multi-Functional Water Pressure Linkage Valve Water Heater Dedicated

Product Overview
This pre-assembled brass water gas linkage valve assembly with built-in pulse solenoid valve is the core dual safety control component of tankless gas water heaters. It takes water pressure as the driving signal to control gas supply: when hot water tap opens, water pressure pushes the internal linkage core to open the main gas channel, meanwhile the matched solenoid valve is energized to open auxiliary gas circuit for ignition; once tap closes or water pressure is insufficient, mechanical structure and electromagnetic valve double cut off gas supply to avoid dry burning and gas backflow risk. The whole valve body adopts thick forged brass anti-corrosion material, equipped with independent water temperature & firepower adjustment shafts and pre-wired quick plug harness, perfectly adapt to long-term high temperature humid working environment inside water heaters, widely used as aftermarket replacement spare part for damaged original integrated valve assemblies of household gas water heaters.

Main Advantages
Dual Mechanical + Electromagnetic Safety Protection
Two sets of independent gas cut-off systems work together, eliminate the hidden danger of gas leakage and dry burning caused by single valve core failure, greatly improve household gas safety.

Anti-scale Solid Brass Valve Body
Integral forged brass effectively resist mineral scale deposition, avoid valve blockage that often occurs on alloy or iron valves after long service.

Independent Winter & Summer Temperature Regulation
Separate adjustment shafts for water flow and gas flow, users can adjust hot water temperature freely without overheating or cold water fluctuation during shower.

One-piece Quick Replacement Design
All supporting electronic and mechanical parts pre-installed as a unit, technicians only need to connect water & gas pipelines and plug wire terminal to finish replacement.

Anti-interference Stable Solenoid Operation
Shielded solenoid coil with stable suction, no ignition failure caused by weak magnetic force under low voltage.

Wide Compatibility for Dual Gas Models
Suitable for natural gas and LPG propane tankless water heaters, just match corresponding gas nozzle to switch gas type.

Installation Tips
Confirm the matched gas nozzle (Natural Gas / LPG) before installation to avoid incomplete yellow flame combustion.

Wrap raw tape around all brass thread joints, test water & gas tightness with soapy water after full installation.

Insert the 4-core wire plug fully into the main control board socket to prevent poor contact leading to solenoid not working.

Do not bend the connecting silicone pressure tube sharply to avoid blocking water pressure signal transmission.

FAQ:
What is the primary function of this valve?
Answer: It coordinates water flow and gas supply, enabling safe ignition of the gas water heater even at zero or extremely low water pressure.

Does it fit all gas water heaters?
Answer: It works with most zero water pressure gas water heater models. Please check the specifications before purchase.

Is it suitable for areas with low water pressure?
Answer: Yes, this valve is specifically designed to work in areas with weak or unstable water pressure.

Do you offer OEM or customized services?
Answer: Yes, we provide OEM & ODM services tailored to customer specifications.
