Valves

Valves come in many shapes and forms. Valves are necessary for the continued operation of your process. L-R Systems' engineering and design staff produces several standard lines, and can custom-create equipment to suit your company's needs for sizing and applications. We produce:

Airlock Valves

Airlocks allow the passage of product between two points - whether it's pressure, vacuum or atmospheric conditions. L-R Systems engineers design standard and customized airlock application for a variety of industries and uses.

Butterfly Valve

  • Gravity flow or pressure systems up to 200 psig (through 12" sizes) and 150 psig (14" and above)
  • Excellent choice for sealing receivers, hoppers and convey lines and great for accurately dispensing material or products
  • Horizontal or vertical valve orientation

Slide Gate Valve

  • Gravity flow or dilute phase pneumatic conveying
  • Aluminum, and stainless construction available
  • All types of material – excellent for granular products with options for fine powders
  • Horizontal or vertical valve orientation
  • Positive material and air seal to atmosphere available
  • Used for maintenance gates, flow stopping, discharge control applications

Options Include:

  • NEMA 12 to NEMA Electricals
  • Full line of proof of positioning switches for valve position indication
  • Full range of line sizes with plain stubs or flanged connections

Looking for valves for your processing application? Try the experts at L-R Systems. We have years of experience designing and creating industrial processing and manufacturing equipment, and we're excited to go to work for you.

Diverter Valves: L-R Systems offers pneumatic conveying, flex tube, fill pass, multi-port and gravity flow diverter valves.

Proportioning Valve: Our external proportioning valve assemblies allow loading two different materials into an auto hopper loader. It is an affordable way to combine virgin and regrind at the machine throat.

Scale Valves: L-R Systems offers fill pass diverter/ scale valves that can accommodate multiple conveying lines.

Vacuum Control Valve: High-quality vacuum control valves are necessary for the continued operation of a vacuum conveying system.
