Supplier product
Baoding Pingyilu Petroleum & Natural Gas Fittings Co., Ltd.
Stainless gate-valve selection with several nominal-pressure entries.
The Z41W listing identifies stainless construction for the body, bonnet, gate and stem, with a copper-alloy stem nut. Pingyilu describes full-open and full-closed service and expressly excludes throttling. The published table gives 1.6, 2.5 and 4.0 MPa entries and mentions nitric-acid service, which requires confirmation of the actual stainless grade and solution conditions.
