Shanghai Zhibang Valve Manufacture Co., Ltd. is a professional manufacturer with over 8 years of experience in valve production and export. Our Spring Loaded Check Valve Flanged End 150LB Carbon Steel is specifically designed for demanding oilfield pipeline applications, offering reliable backflow prevention and long service life. With a robust spring-assisted closure mechanism, this valve ensures rapid response and minimal pressure drop, making it an ideal choice for horizontal or vertical piping systems. Backed by our ISO9001 certified quality management system, each valve is rigorously tested to meet international standards.
This check valve features a compact, durable carbon steel body (WCB/WCC) and a flanged end connection conforming to ASME B16.5, Class 150. The spring-loaded disc ensures positive sealing even under low flow conditions, preventing reverse flow and protecting downstream equipment. Perfect for oilfield pipelines, water injection systems, and process lines, our valve delivers consistent performance in harsh environments.

Frequently Asked Questions
-
What is the difference between a spring loaded check valve and a swing check valve?
Spring loaded check valves use a spring to close the disc quickly, preventing backflow even at low flow rates. Swing check valves rely on gravity and flow direction, which can cause slamming and are less suitable for vertical installations. -
Can this valve be used for vertical piping?
Yes, the spring mechanism ensures reliable closure regardless of orientation. For vertical upward flow, the spring assists the disc to close when flow stops. -
What is the maximum operating pressure for 150LB rating?
Class 150 corresponds to a maximum working pressure of approximately 285 psi at ambient temperature, per ASME B16.34. For higher pressures, custom ratings are available upon request. -
Do you offer soft seat options for tighter shutoff?
Yes, we can provide PTFE or Nylon seat inserts for bubble-tight sealing. Please specify your requirement when ordering. -
What standards do your flanges comply with?
Flanges are designed and manufactured per ASME B16.5, Class 150, with raised face or flat face drilling. Other standards (e.g., DIN, JIS) are available upon request. -
How long is the delivery time?
Typical delivery is 15–30 days for standard sizes. Custom orders may require 30–45 days. We ship from Shanghai, Guangzhou, Hong Kong, or Beijing. -
Is the valve factory tested?
Yes, each valve undergoes hydrostatic shell test and seat leakage test according to API 598. Test reports are provided. -
Can you provide a coating or lining for corrosive fluids?
We offer optional epoxy coating, hot-dip galvanizing, or rubber lining. Please consult our sales team for specific requirements.
