Frequently Asked Questions
What are the testing pressures for these valves?
The shell pressure test is conducted at PN × 1.5 times, while the seal pressure test is executed at PN × 1.1 times, supporting nominal operational pressures of 1.0~2.5MPa.
What media and operating temperature are supported?
These valves are engineered for water, oil, gas, and related media, with an allowable operating temperature of ≤ 80℃.
What materials are used for the body and sealing components?
The valve body is constructed from grey cast iron, ductile iron, or cast steel. Sealing components incorporate NBR rubber rings and ductile iron plates encapsulated in resilient EPDM or NBR.
Which stainless steel grades are available for the valve stem?
Valve stems can be configured with multiple grades including 45#, 1Cr13, 304, 416, and 316 stainless steel to suit specific operational requirements.
What size ranges are covered in the dimension specifications?
The standardized connection dimensions range from DN50 up to DN600, with comprehensive flange drilling configurations for both 1.0MPa and 1.6MPa pressure classes.
How are the finished valves packaged for transport?
Finished valves are protected with dust covers and packed in industrial-grade crates or secured pallet formats to prevent transit damage.
