POLY-SD Bursting Disc Scored, Forward-acting

Description

The versatile Poly-SD bursting disc can be used in liquid, vapour and two phase flow and is available in a large variety of materials. Specifically designed to help prevent material buildup on the bursting disc, the Poly-SD is ideal for polymerisation processes.

  • Provides pressure relief at or below its rated burst pressure, even if damaged or installed upside down
  • Different scoring configurations offer optimised performance over a wide range of pressures.
  • Operates in liquid, vapour and multi-phase media applications
  • Can be operated as high as 95% of rated burst pressure
  • Can withstand full vacuum without vacuum support, in a wide range of pressures
  • Non-fragmenting
  • Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves
Design Scored, Forward-acting
