Applications

On/Off and Control Applications in: Pulp and Paper, Sugar and Ethanol Production, Mining, Oil and Gas, Power, Refining, Chemical, Food and Beverage, HVAC, and other highly abrasive slurry applications.

Bray's Flow-Tek Series S19 combines the shearing action of a knife gate valve, control characteristics of a globe valve, and sealing performance of a ball valve in a versatile high-performance rotary control valve designed for throttling and on-off applications. The Series S19 segmented valve features a characterized segment for high rangeability and high flow capacity in an economical product that delivers exceptional control valve performance. Series 19 segmented ball valves also deliver excellent sealing performance for on-off applications, achieving Class VI in resilient and Class IV sealing performance in metal seated trims.

Bray's Flow-Tek Series S19L segmented Control Ball Valve combines the versatile design of the standard S19 with advanced trims for highly abrasive slurry and severe service applications that often lead to erosion in traditional valves. Bray's proprietary advanced coating technology is applied to the internal components of the valve to provide increased hardness and bond strength over other commonly used coating technologies throughout the industry. Series S19 & S19L segmented valves are available in a variety of trim configurations for use in a wide variety of industries including:

Pulp & Paper
Sugar & Ethanol
Refining Process Control
Power Plants
Hydromet Pump Isolation

Process Control
Food & Beverage
HVAC
Solvent Extraction
Mining

Water & Wastewater
Oil & Gas
Chemical
Gas Collection Fields

S19-cutaway-min-2

Series 19

The perfect control ball valve solution for slurries containing suspended solids or fibers. viscous fluids, pulp, paper, chemical, wastewater sludge, and other challenging service conditions.

A. One-Piece Body

Provides a rigid, robust shell capable of withstanding pipe loading, and eliminates potential leak paths.
B. Splined Stem to Segment Connection

Provides efficient torque transmission and precise control, with low hysteresis and reduced deadband.
C. Self-Centering Ball Segment

Perfectly oriented, specially designed shaft pin facilitates self-alignment of the ball segment, while simplifying assembly and disassembly during routine maintenance.
D. Coatings

High-performance coatings on internal components ensure long life and corrosion resistance.
E. Energized Seat

Seat spring provides constant force on the seat to seal against the segment at low differential pressures. At higher differential pressures, optimized sealing diameters ensure lower seat torques.
F. Protected Sealing Area

Seats are designed to direct media flow away from the sealing area.
G. Blowout Proof Stem

Retaining ring fits between machined stem groove and gland retainer step.
H. Easy Maintenance

The seat is replaceable without removing the segment and shaft.

s19l-cutaway-min

Series 19L

Severe erosion demands more from your flow control valve. In addition to the benefits of the standard service valve, the S19L offers advanced material selections and multiple trim options to provide an application-specific solution for your unique needs.

A. Erosion Resistant Downstream Liners/Seats

Reverse flow direction prevents body wall erosion due to high velocities at low openings.
B. Severe Service Coatings

Customized ultra-hard coatings provide application-specific corrosion and erosion resistance for valve internals.
C. Bearing Seals

Protects metal bearings from ingress of media.
D. Pressure Balanced Seat Design

Seats capable of sealing under full differential pressures with low torques and smooth operation.
E. Easy Maintenance

Flanged retainer with uninterrupted gasket surface provides easy access for seat and liner replacement.
F. Trim Options

Multiple options available for optimized performance in various levels of erosive services.
