Application scenarios
Slurry Transfer Pipeline Flow Control
Installed on process transfer pipelines carrying slurries with solid particles to regulate or limit slurry flow. The Series 39 is designed specifically for slurry control and features a hardened chrome-moly iron disc and wear-resistant liner, making it suitable for conditions involving slurry-induced wear.
Process Pipeline Control for Erosive Particulate Media
Installed in process pipeline sections carrying solid particles that continuously erode the valve flow passage, for flow control or shutoff. The Series 39 features a hardened chrome-moly iron disc and wear-resistant liner, making it suitable for erosive applications.
Control of Corrosive Slurry Handling Systems
Installed on slurry handling pipelines carrying corrosive components and solid particles to control the flow of the medium. The Series 39 is specifically suitable for corrosive applications and features a wear-resistant liner design with optional metal body materials.
Process Pipeline Control for Scaling Media
Installed on process pipelines where deposits or scale may form to regulate or isolate the medium. The Series 39 is specifically suitable for scaling media and slurry control applications.
Selection points
Hardened Chromium-Molybdenum Iron Disc and Wear-Resistant Lining Materials
The disc is made of hardened chromium-molybdenum iron, while the lining uses wear-resistant materials such as metal carbides and ferrochrome alloys, making it suitable for slurry and erosive or corrosive media control applications.
Wafer-Style or Flanged Long-Body Design Available
The valve is available in wafer-style and flanged long-body configurations, allowing selection based on piping connection requirements and installation conditions.
Installation & maintenance notes
Pressure and Temperature Operating Limits
Before installation and commissioning, confirm that actual operating conditions do not exceed the maximum allowable operating pressure of 230 psi (16 bar) and that the operating temperature is within the range of -29°C to 150°C.
Verify Mating Flange Specifications
Before installation, verify that the mating pipeline flanges match the valve connections. The valve flange drilling complies with ASME B16.5 Class 150.
FAQ
What media and service conditions is the Series 39 Slurry Control Valve suitable for?
It is suitable for slurry, erosive, corrosive, and scale-forming media, primarily for high-wear slurry control applications.
What are the main technical specifications of the Series 39 Slurry Control Valve?
The size range is NPS 2 to 24 (DN 50 to 600), the temperature range is -29°C to 150°C, and the maximum allowable operating pressure is 230 psi (16 bar). Body materials include ductile iron, stainless steel, and carbon steel.
What liner and disc materials are available for the Series 39 Slurry Control Valve?
Available liner materials include chrome iron, tungsten carbide, or Abrasituff. The disc is made of hardened chrome moly iron. The specific configuration must be confirmed according to the actual model and application conditions.
How is an actuator connected to the Series 39 Slurry Control Valve?
The valve features a double-D stem design and an ISO 5211 top plate, supporting direct mounting of Bray actuators. Body types include wafer and flanged long-pattern bodies.
Does the Series 39 Slurry Control Valve provide sealing, and what are its maintenance features?
The Series 39 is a control valve, and its disc does not provide shutoff capability. Its design maximizes flow while reducing wear. The stem packing is accessible without removing the actuator, and the stem is fitted with a blowout-proof retaining ring system. The specific maintenance plan must be confirmed according to the actual model and application conditions.
