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.

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.

Pressure Range: 2000 PSIG
Material of Body: Stainless Steel
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.

In 1997 Microtork in Warren, NJ purchased the assets of Rotovalve located in Rahway, NJ. The valve design of Rotovalve was based off the original principles of the Microtork. The original Rotovalve models are manufactured by Microtork. See models for all Microtork and Rotovalve products.
