Gate Valves

Gate valves are ideal for handling dry bulk material in gravity flow, dilute phase or dense phase pneumatic conveying applications. Enge Plas’ range of gate valves are designed and engineered with two main principals in mind:

  • extend the service life of the gate valve and
  • perform maintenance without taking the gate valve out of line

Our gate valves serve many industries including chemical, cement, coal, food, frac sand, grain, minerals, petrochemical, pharmaceutical, plastics, polymer, rubber and mining.

Key Benefits

  • Unlike common knife gates and butterfly valves, our gate valves are specifically engineered to handle dry bulk powders, pellets, and granules.
  • Knife gates rely on soft elastomeric seals which erode or tear away in service.
  • Butterfly valves incorporate discs that cause significant flow restrictions, thus impacting system performance and throughput.
  • Both designs promote wedging and packing of materials, preventing positive air and material shut off.
  • Our gate valves eliminate design flaws associated with knife gates and butterfly valves.

Typical Key Features

  • Serviceable while in-line
  • Wear compensating hard polymer seals
  • No pinch points or exposed moving parts for safe operation
  • Open / closed or volume metering of material
  • Accurate metering of materials with optional metering controls
  • Horizontal or vertical valve orientation

Diverse Range

  • Orifice Gate
    • Handles dry bulk solids in gravity flow, dilute phase, or vacuum conveying systems with pressures up to 1 bar
    • Mechanically self cleans on opening stroke
    • Seals protected from material flow stream
  • Roller Gate
    • Best choice for handling dry material in gravity flow or low-pressure applications
    • Positive seal of dust and fine powders
  • HDPV2 Gate
    • Address higher-pressure applications up to 5 bar
    • Seals fine material in higher aeration or pressure applications
    • Patented rising blade action ensures optimal seal
    • Seals protected from blast abrasion
    • Does not pack material upon closure
  • TSG Gate
    • For the most demanding applications when handling heavy-duty abrasive materials such as sand, gravel, coal, and whole grains in gravity flow applications where positive material shut-off and dust tight sealing is required
  • Titan Pressure Gate Valve
    • Address higher-pressure applications up to 6.8 bar and higher temperatures up to 350°C, for highly abrasive applications and requires minimal maintenance over the life of the valve
    • Mounting boss for the addition of an optional proximity switch
  • Clear Action Gate
    • For use in gravity flow or pneumatic conveying systems up to 1 bar
    • Self-cleaning action on closure minimizes material build-up
    • Positive seal across the valve and to atmosphere
    • No internal cavities for material to build up
  • Aggregate Gate
    • For demanding applications handling material such as sand, gravel, whole grains, and coal
    • Narrow profile, choice of actuators, and custom rectangular sizes make this slide gate adaptable to most existing installation
    • Replaceable abrasion resistant liners deflect material away from support rollers
    • Hardened steel rollers with grease fittings
    • Material displacement pocket minimizes wedging of material as blade closes
  • Rounded Blade Gate
    • For the most demanding applications when handling heavy-duty abrasive materials in gravity flow where positive material shut-off and dust-tight sealing is required
    • Design allows for rapid actuation to quickly start and stop material flow and makes it a good choice for applications that require metering
  • Maintenance Gate
    • Designed to shut off material from a hopper or silo when maintenance of downstream equipment is required
    • In open position, it positively seals conveying air and material to atmosphere
    • Hand crank gearing is designed to close through material in case of an upset condition
  • Hand Slide Orifice Gate
    • To handle dry bulk solids in gravity flow conveying
    • Full flow orifice provides unrestricted conveying of material with no disk or ledges to impede flow or cause material bridging
  • Quick Clean Orifice Gate
    • “Clean out of place” gate valve designed for frequent cleaning
    • Features a full-port opening and self-cleaning design
    • Can be disassembled and assembled in minutes without tools
    • Carries a USDA Dairy Standard Accepted rating and is an excellent choice for sanitary applications
