Robust globe control valves
August 2013
Valves, Actuators & Pump Control
PSV Mitech’s general-purpose globe control valves have been tried and tested and are proven to be successful in both complex and basic applications. The standard valve can be used for many applications and offers high positioning accuracy and tight shut-off, together with compact size and robust construction. Due to the modular design it can be easily adapted to satisfy special requirements such as high or low temperature, corrosive duties, three-way configuration and high pressure drop applications.
Various types are available, from the standard valve up to the specially designed severe service valve in 1,3 to 61 cm NB and up to ANSI 4500. The valves feature tight shut-off, low noise, cavitation control and energy dissipating trims. The body materials are manufactured from carbon steel, stainless steel, bronze, chrome moly and special alloys, ideal for high pressure and extreme operating conditions. There is a choice of 2-port globe, 3-way globe, 2-port angle and sweep angle, in sizes from DN15 to DN600.
PSV Mitech control valves utilise the clamp-in-place, free-float design. All trim components are designed to clamp in place so the valve can be quickly configured to the user’s specific process needs. The free float of the seat and plug during assembly means that stem, plug and seat alignment are easily achieved. When compared to alternative designs, the free-float design provides the user with longer stem seal life and better valve shut-off performance. The simple design also means that maintenance is quick and easy, with no special tools required to achieve the design performance of the valve. The valve has been specially designed for applications within the petrochemical, mining, food and beverage, pulp and paper and power generation industries. PSV Mitech’s valve body and trim designs are supported by extensive computational fluid dynamics (CFD) analysis.

Selection of two-port valves: an open and shut case
SMC Corporation South Africa
Valves, Actuators & Pump Control
Little consideration is generally given to two-port valves because they are often perceived as simple devices that only open and close to control downstream fluid supply. Although this is mechanically true, choosing the optimal two-port valve for your application can make a big difference, saving space, weight and energy consumption.
