Product Focus: IsoTech® - Parallel Slide Gate Valve 

Exceptional Durability psg
The Valvtechnologies’ IsoTech® parallel slide gate (PSG) valve addresses the need for true in-line valve reparability in large diameter, high-energy piping systems. Specifically designed for steam and feedwater applications, IsoTech® provides bi-directional, zero-leakage using the HVOF RiTech® robotic thermal coating spray system. It is available in sizes 6” to 36”, pressure classes ANSI 300 to 4500, and can be manufactured in any material. When used in power industry applications, the IsoTech® carries the ValvTechnologies' four-year, zero-leakage guarantee.

Relatively high differential pressures are required. IsoTech® valves provide “exact” flow control solution every time, from minimum or normal control to full rangeability across a wide-range of pressure drops and conditions.

What differentiates the IsoTech® valve? 
The ValvTechnologies’ IsoTech® has exceptional durability in large part due the use of our HVOF RiTech® hard coatings with a RC 70 seat hardness and are designed for up to ASME/ANSI class 4500 at 1800°F (982°C).

What are the benefits of the PSG valve?

  • No thermal binding – lockup
  • Full bi-directional isolation for outstanding operating flexibility
  • Long service life – sealing surfaces are overlaid with Tungsten or Chromium Carbide Cermets using our exclusive HVOF coating process - allows for exceptional resistance to attacks by abrasives and fluids
  • Extra protection delivered: stem, discs and guides overlaid with Tungsten or Chromium Carbide
  • Cermets using our exclusive HVOF coating process
  • Easy adaptation for bypass and equalization
  • Designed for ease of actuation
  • Designed for in-line maintainability
