Frequently Asked Questions
What is the maximum operating temperature for these valves?
The valves are engineered for efficient performance within an operating temperature limit of ≤80℃.
What types of media are compatible with these products?
The components are suitable for standard working media, including water, oil, gas, and similar fluids.
What nominal pressure ratings are supported?
The nominal pressure range spans from 1.0 to 2.5 MPa, with a shell test pressure factor of 1.5 times and a seal test pressure factor of 1.1 times.
What materials are used for the valve stem and sealing elements?
Valve stems are crafted from stainless steel options (45#, 1Cr13, 304, 416, 316), while seals and gaskets are constructed with durable NBR or EPDM elastomers.
What sizes are available in this product line?
Standard nominal diameters range from DN50 up to DN400, covering standard pipe and connection configurations for industrial pipelines.
How are the valves prepared and packed for shipment?
All units are securely mounted on heavy-duty wooden skids or packaged in protective shipping crates to prevent movement, surface damage, and impact during transit.
