Features and Benefits

Series 39 Slurry Control Valve Features and Benefits

A Adjustable Packing

Easy access to stem packing without removing the actuator.

B Direct Actuator Mounting

One-piece high-strength 17-4PH stainless steel on all sizes. Bray’s double D stem design and ISO 5211 top plate allow direct mounting of Bray actuators, reducing packaging complexity.

C Engineered Stem Bearings

Upper stem bearing features 316 stainless steel housing with TFE/glass lining, lower stem bearing features PSZ ceramic material for exceptional corrosion resistance and resistance to deformation from mechanical load and high temperature.

D Blowout-Proof Stem

A retaining ring system is installed to ensure complete stem retention in the event of an internal stem failure.

E Valve Lining

Bray offers three material options to meet different service requirements and extend product life: chrome iron, tungsten carbide, and Abrasituff material. This design is built to last and minimizes maintenance costs as only a few parts require servicing.

F Control Design

Series 39 is a control valve whose disc does not provide shutoff capability. The disc is designed to maximize flow and offers material options to minimize wear. The valve is capable of 360-degree rotation.

FAQ

What media and operating conditions is the Bray Series 39 slurry control valve suitable for?

The Series 39 is suitable for slurry, erosive, corrosive, and scaling media applications, primarily for slurry control requiring high wear resistance. Its temperature range is -29°C to 150°C with a maximum allowable working pressure of 16 bar. Specific configuration should be confirmed based on actual media characteristics, temperature, pressure, and abrasion level.

Can the Series 39 valve disc provide reliable shutoff and sealing?

The Series 39 is positioned as a control valve. Its disc is designed to maximize flow capacity and reduce wear, and does not provide sealing capability. Therefore, this series should be selected for slurry flow control needs and should not be used as a valve requiring disc sealing shutoff. The disc can rotate 360 degrees.

How to select lining and disc materials for the Series 39 based on different abrasive media?

The Series 39 offers lining material options including chrome iron, tungsten carbide, and Abrasituff. The disc is hardened chrome-moly iron. Material selection should consider media particle characteristics, corrosiveness, erosion level, and operating conditions to balance wear life and application requirements.

How can the Series 39 be connected to actuators?

The series features a one-piece high-strength 17-4PH stainless steel stem, double D stem design, and ISO 5211 top plate for direct Bray actuator mounting. The direct-mount design helps reduce packaging complexity for actuator installation.

What design advantages does the Series 39 offer for stem packing and bearing maintenance?

The Series 39 stem packing is directly accessible and can be adjusted without removing the actuator. The upper stem bearing uses a 316 stainless steel housing with TFE/glass lining, and the lower stem bearing uses PSZ ceramic for enhanced corrosion and deformation resistance. The valve lining design also minimizes the number of components requiring maintenance.
