The burst test is a crucial evaluation for faucet ceramic cartridges characteristics. It's designed to prevent leakage stemming from the water hammer effect, which typically happens when a valve abruptly closes at a pipeline's endpoint. For faucets, we subject the valve cartridge to two testing conditions: valve closure and outlet closure (end point close). If the ceramic disc serves a diverting purpose, a burst test isn't essential. Our design team meticulously examines the cartridge body's structure and emphasizes the sealing part's smoothness. These elements are pivotal in successfully passing the burst test. During production, our quality assurance team periodically selects cartridges for comprehensive testing, ensuring they uphold our highest standards. Read More
The sensitivity test evaluates the precision of temperature control in faucet valve cartridges, and the ceramic disc's design is crucial to achieving this sensitivity. While the handle's length can influence temperature, during the design stage, we prioritize considerations like water backflow and sealing area to guarantee optimal sensitivity. Notably, between 34°C and 42°C, our faucet valve cartridges outperform competitors, boasting unparalleled sensitivity worldwide. Read More
