1. Product Description
An Angle Pattern Screw-Down Non-Return (SDNR) Globe Valve combines isolation, flow control, and non-return functions in a compact 90-degree body configuration. The angle design directs flow at a right angle, reducing the number of pipe fittings required and minimizing pressure drop .
The “Screw-Down” feature allows manual closure by screwing the stem down to force the disc onto the seat. The “Non-Return” function enables the disc to act as a check valve when the stem is fully raised, automatically preventing backflow . The C95800 body material offers exceptional resistance to seawater corrosion, cavitation, and biofouling, making it ideal for marine and offshore applications .

7. Design Features
-
Angle Pattern Design: The 90-degree body configuration eliminates the need for an additional elbow fitting, reducing installation costs and pressure drop .
-
Screw-Down Mechanism: The threaded stem allows manual closure of the valve independent of line pressure, providing positive shut-off when required .
-
Non-Return Function: When the stem is fully raised, the disc is free-floating and acts as a check valve, automatically closing when flow ceases or reverses to prevent backflow .
-
C95800 Aluminium Bronze Body: Exceptional resistance to seawater corrosion, cavitation, and biofouling; high strength and wear resistance; non-sparking for hazardous environments .
-
Guided Disc: The disc is guided by precision-machined surfaces in the body or bonnet, ensuring proper alignment during both manual closing and automatic check operation.
-
STL Hardfacing (Optional): Sealing faces can be overlayed with Stellite for enhanced wear and corrosion resistance, ensuring long service life in demanding applications.
-
Renewable Seat Ring: The seat ring is typically threaded or welded-in, allowing for field replacement without replacing the entire body.
-
Blow-Out Proof Stem: The stem is designed with an internal shoulder that prevents ejection under pressure.
-
BS/EN Compliance: Designed and manufactured to British and European standards, ensuring compatibility with UK, European, and Commonwealth pipeline systems.
8. Applications
