Double Hinged Bellows - DHF - 1.5 to 48 ins (40 to 1200mm)

Contains two stainless steel bellows which are joined by a common connecting pipe . Functions through angulating each bellows in opposite directions in order to provide lateral movement in one plane only. Hinged tie bars absorb thrust from the pressure loads which results in low anchor forces. The amount of lateral deflection is proportional compared to the distance between the bellows centres.
