This versatility ensures compatibility with most plumbing setups, enhancing installation ease and flexibility. [Constructed from Safe, Stainless Steel] Crafted from 304 stainless steel, this auto-fill shutoff valve ensures safety for potable water applications. Its robust construction resists wear and impact, affording a prolonged service life. It is lead-free, ensuring continual use without degradation. [Efficient and Maintenance-Simple] Compact and efficient, this valve delivers reliable water flow performance. Installation is straightforward, reliability is high, and maintenance is minimal, thanks to an integrated filter that protects against sediment, guaranteeing uninterrupted operation. [Applicable in Multiple Scenarios] Suitable for a range of applications including solar water tanks, livestock troughs, and swimming pools. This non-electric solution operates effectively at pressures above 0.2 kg/cm² and supports water temperatures from 0°C to 100°C.
