Product detail · 详情说明
Valve selection is driven by the media and the seat material, not by the pipe size. PTFE seats suit most water and air duty but soften near steam temperature; a metal-seated or graphite-packed valve is the correct choice there.
Specify the connection standard, media, working pressure and temperature. We confirm the seat and packing combination from the manufacturer table and can quote a lever, gearbox or pneumatic actuator on the same line.
选型与验收要点 / Selection & acceptance points
- Thread, flange and sanitary connection options stated separately
- PTFE / RPTFE / metal seats matched to media temperature
- Manual, gearbox or pneumatic actuation on one RFQ
- Body material and pressure class confirmed on the datasheet

Frequently Asked Questions
Send the part number, a photo of the nameplate / old part, or the machine model and required dimension. We reply with the applicable standard designation and a factory datasheet; the final specification is fixed on the proforma invoice.
Commercial invoice, packing list, certificate of origin, bill of lading or AWB, and an HS-coded technical datasheet. The HS 6-digit heading shown on this page is the international classification; your clearing agent confirms the Pakistan 8-digit PCT subheading and the duty rate applicable on the date of import.
No. The location named under 'Typical sourcing base' is a publicly known industrial cluster, given to help you understand the supply chain. The actual factory, country of origin and any mill / test certificate are confirmed in writing on the quotation and the certificate of origin. Treat it as [待确认] until then.
