Application

To provide controlled resistance in riser branches.

Description

Semi lugged carbon steel high performance butterfly valve, fitted with gear operator for infinitely variable settings and stainless steel memory stop feature (DRV) to precisely set and retain the desired maximum opening position differential pressure. Once set, the valve can be closed and re-opened accurately to the pre-set differential pressure.


The product is a commercially attractive option compared to traditional Globe-style double regulating valves. The butterfly valve concept is space saving and easier to support when weight is a concern. The valve is also available in large sizes up-to and including 800 mm diameter.


Features and benefits:

  • PN40-50 (size dependent) double regulating wafer type gear operated butterfly valve
  • Temperature range -29°C to 225°C
  • Sizes: 50 – 400 mm, larger sizes available on request
  • Robust and easy to install and operate semi lugged gear operated butterfly valve
  • Easy to set accurately, positive position and reset memory stop feature
  • Stainless steel memory stop feature (DRV) 
  • Bureau Veritas Certification
  • Testing according to API 598
  • Light weight and cost-effective.


Memory Stop Application:

The stainless steel memory stop feature (DRV) sets and retains the desired maximum opening position and differential pressure. Once set, the valve can be closed and re-opened accurately to the pre-set differential pressure.
