Control valves

At system design stage design engineers most often select control valve of the same diameter as pipeline diameter. For our offered control valves we have software program which allow us to select precisely control valve depend on given data.

We need the following data for control valve selection:
• Working media
• Maximum flow
• Minimum flow
• Inlet pressure
• Outlet pressure
• Maximum temperature
• Minimum temperature

For example: our company selected and supplied control valve for company “Daugavpils Siltumtikli”. This valve should be installed on the natural gas supplying to the boiler pipeline with diameter 300 mm. This boiler has 12 burners, which, depend on operating condition, can operate all together or just two of them. In such conditions control valve operating regime is very hard: differential pressure is from 6 bar a up to 1.3 bar a and capacity decrease or rise 6 times. Based on these technical parameters, we selected 65 mm control valve with a metal to Teflon seat ring, control element was made of “Stellite“, with noise level reducing mesh. This control valve (which perfectly operates 5 years with noise level up to 50 dB) was 3 times cheaper then 300 mm control valve made in Russia.

Our control valves advantages in that they are universal and suitable for different mediums: heavy fuel oil (mazout), steam, natural gas, water and many others.
