Linhai Huali Apparatus Co., Ltd supplies frost proof yard hydrants designed to prevent freezing in cold climates by positioning the valve below the frost line. The unit consists of a vertical pipe with a check valve and drain mechanism that automatically empties water after use. The body is constructed from cast brass with a corrosion-resistant finish, and the operating handle is ergonomically designed for single-hand operation.
The hydrant operates using a stem-and-gear mechanism that lowers the valve assembly below the frost line, typically 1.2m to 1.5m deep, depending on installation depth. When the handle is turned off, gravity drains residual water from the vertical chamber, preventing ice formation. The inlet is threaded to standard 3/4 inch NPT, and the outlet has a 3/4 inch female hose thread. The unit is rated for continuous operation at pressures up to 10 bar.
These hydrants are used in residential landscaping, agricultural irrigation, and construction sites in regions with freezing winters. Buyers include irrigation contractors, farm equipment suppliers, and municipal maintenance departments. The product is shipped in bulk, typically 10 to 50 units per carton, packed in foam-lined boxes. Lead time is variable and depends on order volume. Payment is typically arranged via T/T or L/C.

Before ordering, confirm the exact inlet and outlet thread sizes and verify compatibility with local plumbing standards. Request a sample to test the drain function under simulated use. Ensure the brass casting has no visible porosity or casting defects. Do not accept units with visible scratches on the nickel plating, as this may indicate poor surface treatment.
Confirm the Incoterms - FOB Ningbo or FOB Shanghai are typical. Lead time is generally 25 to 45 days for bulk orders. Packaging must include individual foam inserts and corrugated cartons to prevent damage during transit. Payment terms are commonly 30% deposit with balance against bill of lading. Request a packing list with itemized weights and dimensions.
Perform a pressure test at 1.5 times the operating pressure (15 bar) before installation. Check for leaks at the stem seal and drain port. Inspect the finish for uniformity and absence of flaking. Request a quality control certificate from the supplier’s production line, including batch number and test results for pressure and drainage performance.
