Monoblock valves are simpler than sectional valves and monoblock valves can work under higher pressure. The body type of the valve permits higher pressure because of robust, covered structure.
Sealing of monoblock valve are better than sectional valves so applications which uses higher pressure than 350 bar prefer monoblock valves. Burst pressure of the monoblock valves are around 700 – 900 bar so it can work safely under 350-400 bar. Mostly monoblock valves do not have auxiliary valves such as anti-shock or anti cavitation valves.
