The charging valves from LD Plumbing Co., Ltd are precision-engineered fluid control components designed for hydraulic and pneumatic systems requiring controlled pressure input. Constructed from forged brass or stainless steel 316, these valves feature a poppet or ball-seal mechanism with a maximum operating pressure of 400 bar. They are machined to tight tolerances to ensure leak-free performance under dynamic flow conditions.
The valve bodies comply with standard DIN 28100 or ISO 4400 dimensions for industrial charging fittings. Common variants include direct-mount, inline, and angle configurations with NPT or metric thread options. The sealing elements are typically Viton or EPDM, selected based on fluid compatibility. Surface finish is polished to Ra ≤ 0.8 µm to reduce fluid drag and prevent particle retention.
These valves are purchased by manufacturers of construction machinery, industrial automation systems, and mobile hydraulic equipment. Buyers typically order in quantities of 50 to 500 units per shipment, depending on assembly line volume. Trade terms are FOB Taizhou or CIF destination, with packaging in sealed plastic bags inside corrugated cartons. Lead time is approximately 3 to 4 weeks after order confirmation.

Sourcing Charging valves from LD Plumbing Co., Ltd - China Import Guide
Before ordering, verify the material grade of the valve body and seals with a material test report. Confirm that the brass meets CW614N or the stainless steel meets 316L, and request a chemical composition analysis. Do not accept generic labels like 'high-grade brass' without certified data. Inspect the supplier’s quality control process for batch traceability.
Confirm Incoterms with the supplier - FOB Taizhou is standard, but CIF requires clarity on insurance coverage for transit damage. Lead time is typically 3 to 4 weeks. Payment terms are usually 30% advance, 70% against bill of lading. Request a detailed packing list showing valve count, serial numbers (if any), and carton weights to match delivery records.
Inspect valves for surface defects, burrs, or thread damage before installation. Use a thread gauge to verify pitch and diameter. Perform a pressure test at 1.5 times the operating pressure with air or water to confirm seal integrity. Retain a sample from each shipment for failure analysis. Request a certificate of conformity referencing ISO 9001 or equivalent quality system.
