We offer an extensive range of self-acting control valves for a wide variety of applications including, food and beverage processing, tank blanketing, steam cleaning, oil and gas plants, water supply, chemical transfer and more. Our partner, Mankenberg, has been synonymous with expertise and technical know-how in providing optimised self-acting regulators since 1885.
 

These self-acting control valves have always been well-known for their affordability, functional reliability and long operational lifespan. For decades, Mankenberg has been standing for self acting pressure regulators which have convinced customers through their unbeatable quality, cost-effective price and high on-time delivery performance.

Our range of self acting valves includes: 

 

  • Pressure Reducing Valves – stainless steel pressure reducing valves reduce a high and frequently fluctuating pressure to an adjustable constant pressure downstream of the valve. A spring keeps the valve open and this closes as the outlet pressure rises. We offer a range of pressure reducers suitable for any industrial or ultra-high purity application.
     
  • Back Pressure Valves – back pressure regulators or overflow valves control an adjustable constant pressure upstream of the valve. A spring keeps the valve close. As the inlet pressure rises the valve opens. These pressure sustaining valves are available in cast materials for engines or pilot-operated for large pipelines.
     
  • Bleeding and Venting Valves – bleeding and venting valves remove or admit air or gases automatically from/to tanks, vessels or pipelines. They are float-controlled valves which close as the liquid level rises and open as the level falls.
     
  • Condensate & Steam Traps - steam traps automatically drain condensate without loss of steam or gas. They operate instantaneously and are not affected by backpressure or pressure fluctuations. They do not require an external energy input. Our KA2 autodrains are favoured for biogas applications where ATEX approval is required.
     
  • Vacuum Breakers – vacuum breakers protect vessels and pipelines against vacuum. A vacuum can build up when a system is being drained, when it cools down or when a pump fails. Vacuum control valves are pressure reducing or overflow valves which control pressures below 1 bara.
