SAFE Combi-C / REYCO^® Combi-C / SAFE Combi-R

Changeover valves and rupture discs: 100 % stand-by security – even for critical media!

Advantages of a combination safety valve with a changeover valve:

• cost saving due to service without plant downtime
• no loss of medium due to exchange of safety valve
• minimization of risks of hazardous media
• in service case: only lowest disposal costs for critical media
• combination of inlet and outlet with a change over valve minimizes a risk caused by hazardous media
• cost saving due to an additional change over valve in the outlet so that only one outlet pipe is necessary

Advantages of a rupture disc:

• Cost saving due to absolute tightness (no loss of medium)
• Due to zero leakage it is possible to use extremely toxic or flammable media
• Use of media that become solid with contact to the atmosphere, stick together seat / disc or react chemically
