An Excellent Choice for Hydraulic Control in a Variety of Industries
The Microtork valves are four way, high gain, Rotary Mechanical Servo Valves that can sense and control the precise positioning of anything that is controlled hydraulically or pneumatically.  A precise instrument with only one moving part, the valve can be mounted in any position and requires no adjustment. 
A Unique Concept in Hydraulic Controls
The Microtork valve makes for the simplest type of positional feedback system because of the extremely low torque required to operate the valve.
Developed originally for directly sensing the paper edge in an edge guiding application it enabled the designer to build into his mechanism a type of control that has been impossible with previously available components.
The Microtork valve can replace expensive electro-hydraulic in many applications. It is one of the most economic and reliable methods of positioning, sensing and following.
Features:
  • Designated for hydraulic use up to 3000 PSIG
  • Stainless Steel internals with Aluminum, Steel, or Stainless body
  • An extremely low force of only a few inch-ounces of torque is required to rotate the valve stem, which in turn controls up to 3,000 PSIG of hydraulic pressure.
  • Sensitivity and gain adjustments are easily made by changing the length of the control arm
  • Valves are designed with a slight “negative lap” which keeps both ports closed f when the valve is in the neutral or null position
Common Applications:
  • Loop and Tension Control
  • Flying Shears
  • Positioning and Locating
  • Following Templates and Cams
  • Coil and Remind and Unwind Machines
  • Maintaining level with a Pendulum Feedback to Valve
  • Web Guiding for Belts, Paper, and Metal
  • Speed Control
Advantages:
  • Simple Mounting and Piping
  • No Electrical Connections
  • Special Configurations and Designs Available Upon Request
 
Microtork Models
 
Model 187 HSL
The Model 187 HSL was the first of the Microtork series of valves ever developed and was designed to absolutely minimize rotation drag on the shaft.
Pressure Range:1500 PSIG
Material of Body:Aluminum
Material of Internals:Stainless Steel
Maximum Flow:3.0 GPM @ 1500 PSIG
Body Configuration:Round
Port Configuration:Radial Orientation / NPT Port Only
Shaft Size:.187 diameter
 
Model 375 SST
The Model 375 SST has identical internal components to the 187 HSL however it uses a larger more robust external shaft. The larger shaft slightly increases seal drag.

Maximum Flow:3.0 GPM @ 1500 PSIG
Body Configuration:Round
Port Configuration:Radial Orientation / NPT Port Only
Shaft Size:.375 diameter
 
Model 375 XLHG
The Model 375 XLHG uses a steel body for increased pressure rating and specialized square flow passages internal to the valve allowing for higher gain.
Pressure Range:1500 PSIG
Material of Body:Steel
Material of Internals:Stainless Steel
Maximum Flow:4.0 GPM @ 1500 PSIG
Body Configuration:Round with Square Backing Plates
Port Configuration:Radial Orientation / SAE Port Only
Shaft Size:.375 diameter
 
Model 375 XLHGHP
The Model 375 XLHGHP uses additional bolts and high pressure shaft seals and orings to achieve higher pressure ratings.
Pressure Range:1500 PSIG
Material of Body:Steel
Material of Internals:Stainless Steel
Maximum Flow:4.0 GPM @ 1500 PSIG
Body Configuration:Round
Port Configuration:Radial Orientation / SAE Port Only
Shaft Size:.375 diameter
Rotovalve Models
 
Model 5
The Model 5 represents a typical servo control valve with a maximum flow of 5.0 GPM
Pressure Range:1500 PSIG
Material of Body:Aluminum or Stainless Steel
Material of Internals:Stainless Steel
Maximum Flow:4.0 GPM @ 1500 PSIG
Body Configuration:Round
Port Configuration:Radial Orientation / NPT or SAE
Shaft Size:.375 diameter
 
Model 10
The Model 10 represents a typical servo control valve with a maximum flow of 7.0 GPM
Pressure Range:1500 PSIG
Material of Body:Aluminum
Material of Internals:Stainless Steel
Maximum Flow:7.0 GPM @ 1500 PSIG
Body Configuration:Round
Port Configuration:Radial Orientation, SAE Port Only
Shaft Size:.500 diameter
 
Model 5SQ
The Model 5SQ has identical attributes of the Model 5 except it is manufactured in a square body style.

Material of Internals:Stainless Steel
Maximum Flow:3.0 GPM @ 1500 PSIG
Body Configuration:Square
Port Configuration:Single Plane / NPT Port Only
Shaft Size:.375 diameter
 
Model "Ashbrook"
The Model "Ashbrook" was specifically designed for the Ashbrook company.
Pressure Range:2000 PSIG
Material of Body:Stainless Steel
Material of Internals:Stainless Steel
Maximum Flow:3.0 GPM @ 1500 PSIG
Body Configuration:Square
