Frequently Asked Questions
Provide size, Class 4500 rating, end type, medium, design pressure and temperature, material requirements, orientation and project standard.
Confirm the pipe schedule, wall thickness, bevel dimensions, bore diameter and applicable welding standard before manufacturing.
No. Body and trim materials must be confirmed from the datasheet and service conditions.
Confirm the flow direction and permitted orientation against the approved valve drawing and project piping specification.
Review the medium, design pressure, operating temperature, required pressure drop, end preparation, material grade, inspection and documentation requirements.
Product Overview
This Class 4500 small-bore check valve is intended for high-pressure steam and process lines where compact construction and dependable reverse-flow prevention are required. The final valve configuration is selected against the purchaser’s datasheet and piping specification.
Weld-end construction supports compact high-pressure piping layouts. Automatic closure helps prevent reverse flow when line pressure drops, while the body and trim materials are selected for the specified medium, pressure and operating temperature.
For procurement review, confirm the end preparation, flow orientation, allowable pressure drop, cracking characteristics, material grade, testing requirements and documentation before ordering. No material grade or dimensional range should be assumed without the approved datasheet.
