Question 1

The stainless steel valve rusts after customers receive the goods.

Accepted Answer

Distinguish material grades clearly before orders. 201 stainless steel is prone to rust in humid coastal environments; offer 304/316 for corrosive working conditions. We conduct pickling and passivation treatment on all valve surfaces to boost anti-rust performance.

Question 2

Valve leakage occurs during customer pressure testing.

Accepted Answer

Confirm working pressure, temperature and medium in advance. Match suitable PTFE/EPDM sealing gaskets. All valves undergo 100% water and air pressure leakage tests before shipment; provide test reports.

Question 3

Customers receive valves with inconsistent sizes or connection standards.

Accepted Answer

Confirm standard types (ANSI, DIN, GB, JIS) and connection forms (flange, thread, weld) at the quotation stage. Mark all dimension parameters on the sales contract and production drawings for double check.

Question 4

Valves are scratched or deformed during long sea transportation.

Accepted Answer

Each valve is wrapped with plastic film and foam individually, then packed in plywood export wooden cases without fumigation. Fix internal valves with brackets to avoid collision.

Question 5

High sea freight and long delivery lead time.

Accepted Answer

Provide multiple shipping solutions: full container load (FCL) for bulk orders to cut unit freight; less container load (LCL) for small batches. Book shipping space in advance to lock lower freight rates.

Question 6

Customs clearance delay at the destination port.

Accepted Answer

Complete full sets of export documents (commercial invoice, packing list, CO certificate, material test certificate, valve inspection report). Classify HS code of stainless steel valves accurately to avoid customs detention.

Question 7

Damaged wooden packaging causes customs fumigation fines.

Accepted Answer

Use IPPC marked plywood cases meeting international fumigation standards to eliminate extra fumigation costs for overseas buyers.

Question 8

Buyers worry about risks of full advance payment.

Accepted Answer

Accept flexible payment terms: 30% T/T deposit for production, 70% balance against copy of bill of lading. Irrevocable L/C at sight is available for large formal orders.

Question 9

Customers request to change valve specifications after mass production.

Accepted Answer

Specification modifications are acceptable only before raw material cutting. Once production starts, changes will generate extra labor and material costs which shall be borne by buyers.

Question 10

Long production cycle leads to customer order cancellation.

Accepted Answer

State clear production lead time in the proforma invoice. Arrange production schedules reasonably; inform clients timely if any production delay happens.

Question 11

Currency exchange loss during payment settlement.

Accepted Answer

Support settlement in USD/EUR/CNY. Lock exchange rate for bulk orders upon customer request to avoid exchange fluctuations.

Question 12

Valves break down after installation at the buyer's factory.

Accepted Answer

Provide professional installation manuals and operation videos. If defects are caused by our production faults, we supply free replacement spare parts or new valves in the next shipment.

Question 13

Customers lack spare parts for later maintenance.

Accepted Answer

Provide long-term spare parts supply for all our valve models at factory cost. List commonly worn accessories (seals, handles, actuators) on quotation sheets for optional purchase.

Question 14

Customers require on-site technical guidance for installation.

Accepted Answer

Send detailed video tutorials for free. For large engineering projects, we can arrange professional engineers for overseas on-site service after negotiating service fees and travel expenses.
