Arrangement f. i. with safety valve Si61/6302...06 Si81/83/84...07

Function

Protection of the plant against pressure exceeding: by means of additional installations a self-operating spring loaded safety valve becomes an „assisted safety valve“.

Application

	High demands with regard to: - stable functioning - tightness until reaction - small closing pressure differences - accurate reaction
	Testability of the safety valves within the system

Design

	For the safety function only one auxiliary energy (pneumatic) is required
	Lifting below the spring test pressure by manual action on site or by external electrical signal
	Operation possible with or without lifting air
	With one control unit it is possible to operate one or more safety valves
