> MOD. 004

Controlled safety pressure relief system CSPRS valves are mainly used where conventional direct-loaded spring action valves cannot guarantee the opening and closing margins that certain specifi c conditions of service demand. The objective is to help the closure by means of pressure so that the valve remains completely watertight until reaching the set pressure and/or to activate the opening with pressure. Once evacuated and in keeping with a previous adjustment, to assist with closing pressure, to once again achieve closure with the desired watertightness. This allows us to:

  • Stabilise the functioning in critical applications of one or several valves.
  • Improve performance, position, repeatability and operational effi ciency.
  • Improve the opening-closure hysteresis.
  • Reduce product losses and minimise them in the case of working with several valves at staggered pressures, if conditions so permit.
  • Increase the operating pressure of the system up to 99.9% of the set pressure.The control safety pressure relief system CSPRS device can be used with any safety valve available in the market and in particular, with models VYC Mod. 485, 486, 494, 495 and 496.

Multi-stage diffusion silencers

> MOD.005 EN ASME/ANSI ASME/FNPT ASME/MNPT ASME/SW….OTHERS TO BE AGREED

During the expansion process for compressible substances such as gases, steam or air, one of the main problems is noise pollution. The noise is caused by opening the valve and discharging the expanded fluid at the speed of sound. Silencers are a great way to reduce this noise, caused by discharging the valve, bringing it down to allowable levels. They are used in places such as power, chemical and petrochemical plants to discharge safety valves, control valves, etc. in pressure lines and equipment that convey compressible substances such as steam, air, carbon dioxide, helium, methane, nitrogen, oxygen and other gases. They achieve noise reductions of more than 50 dB without any additional acoustic absorption materials.
