FSTCDFA - Forward Acting Rupture Discs

Product Description

FSTCDFA rupture discs are composite discs formed by four parts: a slotted, perforated metal part a seal membrane (usually in PTFE but also available in many other metallic or non-metallic materials) a protection section a calibration ring This disc has been designed especially to be mounted on road or rail tankers containing liquids and gas in static, cycling and pulsating conditions. FSTCDFA discs react to excessive pressure with total opening in a few milliseconds. They are therefore recommended for valve protection. Supports may be provided for vacuum or counter-pressure protection.
