  Flowrox Inc.
  Flowrox Knife Gate Valves

  . When a Flowrox Knife Gate Valve is in the open position the two sleeves seal against each other in the center, providing a full bore that allows the slurry to travel through without touching any metallic components. When closing the valve, the gate is forced progressively downward as it nears the fully closed position. At this point, the sleeves are sealed tightly against both sides of the gate so that the line pressure is completely and efficiently contained. How the rubber sleeves work... (read more)

  Rupture Pin Technology
  Model J-A: High Pressure ESV

  HOW IT WORKS. (A) Depressurize Body. (1) Remove Upstream Pressure and downstream pressure. (2) Open vent to vent pressure inside of body. Reclose vent after venting. (B) Reset Clapper. (1) Remove Holding Unit. (2) Remove Buckling Pin. (3) Rotate handle clockwise to reset clapper. (4) Push piston back down. This should hold handle in the operating (horizontal) position. (C) Replace Buckled Pin. (1) Install new pin. (2) Replace top nut. (3) Re-pressurize the system (read more)

  DFT Inc.
  Control Valve

  The control valve with pinpoint modulating control characteristics and a 200:1 turndown ratio for high pressure drop applications. This unique design features a venture ball-cage design. See our website for an animation showing how the valve works. In the full open position, the flow is straight through and operates as a true venturi with inherent high flow and high pressure recovery characteristics. The cage straddles the flow stream and supports the ball on four inclined pads holding... (read more)

  Reduce Compressed Air Usage up to 30%

  cylinder force to move the load, but returns the cylinder with less pressure thus reducing your compressed air consumption by up to 30%. Although reduced, the pressure in port 2 is enough for quick return of the cylinder. The energy saving function is accomplished by action of the spool and works as quickly as a pressure regulator. ADVANTAGES: Reduces compressed air consumption up to 30%. Replaces conventional ISO 5599/I valves without any adaptation. Spool & sleeve construction for long valve... (read more)

  Hydraulic Tank Clean-Out Covers - Tank Access

  and no welding - thus offering a considerable cost savings. Because no welding is required no weld-generated contaminants are introduced into the tank. Available for retro-fitting an existing tank, or for inclusion in new designs, our cleanout covers offer the fastest, most efficient way of providing tank access for service or maintenance. How It Works. When the hydraulic tank is fabricated or updated, two or four tabs are cut when the access hole is formed during laser or plasma cutting. The tabs... (read more)

  Firechek-Heat Activated Pneumatic Shut-off Valves

  Firechek®- How it Works. The shape memory element senses the ambient temperature and through a phase induction change, rapidly produces the force and motion to operate FireChek®. The element is 100% reliable because the shape memory effect is intrinsic to the alloy. Shape memory alloys have performed successfully for years in industrial, military, and consumer product applications. If FireChek® senses temperatures above the shape memory alloy's actuation temperature, the shape memory element... (read more)

  Oil Spray Systems

  . This adjustable air pressure forces the liquid through piping to separate control valves for dispensing or spraying. Any liquid that flows can usually be sprayed, up to 1000 SSU viscosity at 100° F. The lighter the liquid, the easier it is to spray. The amount of liquid sprayed is adjustable from a fine spray, invisible to the eye, to a coarse spray. Learn More.

  Using Ultrasound and Infrared to Predict Failures

  This presentation will review some Infrared and Ultrasound "finds" from the past years. It will then try to show how these two technologies work together to predict an upcoming failure event. We will talk about greasing, alignment, vibration and then show how spectral analysis can assist us in confirming the most common problems that we find in the field. VIEW NOW!. During our discussion of the analytical process, we will use spectral analysis: - to find the harmonic value of a point... (read more)
