　How to choose Schubert Salzer7010 series angle seat valve

Selection of Schubert Salzer7010 series angle seat valveIt is necessary to follow the six steps of "working conditions → specifications → materials → actuators → accessories → compliance", with the core of matching media, pressure/temperature, flow and control requirements, while locking in special scenario requirements such as hygiene/explosion prevention. The following is the selection process and key parameters that can be directly implemented.

1、 Selection core steps (executed in order)

Clearly define the operating condition boundary (basic input)

Medium: fluid/gas/steam, corrosive/abrasive, viscosity ≤ 600mm ²/s, vacuum ≤ 0.001barabs

Pressure: Normal ≤ 40bar (580psi); Three clamp version ≤ 16bar (235psi)

Temperature: Conventional -30 ℃~170 ℃, high temperature can be selected up to 220 ℃, low temperature can be selected up to -100 ℃; Environmental temperature -20 ℃~60 ℃

Scenario: General/Sanitary (Pharmaceutical/Food)/Explosion proof (ATEX)/Oil free/PTFE free, etc

Determine the caliber and connection method

Caliber: DN8~DN80 (1/4 "~3"), sanitary grade is DN15~DN50

Connection: NPT/ISO thread, Tri Clamp, DIN/ISO welded end, pipe end connection, etc

Caliber selection: Match the Cv value with the pipeline flow rate to avoid cavitation or noise caused by high flow rate

Select valve body material (suitable for medium)

Clearly define the application scenario

Industrial fluid control: suitable for fluid control in fields such as chemical production, food processing, bottle filling, steel, polymers, papermaking, solar cells, tire manufacturing, etc.

Harsh working conditions: The valve design is compact and small in size, able to adapt to different installation space requirements, especially suitable for space limited occasions, and can work normally in the temperature range from extremely cold (-100 ° C) to hot (+220 ° C), withstanding working pressures up to 40 bar.

2、 Analyze the characteristics of the medium

Medium type: Suitable for neutral, mildly corrosive, and strongly corrosive media, including gases, vapors, fluids, etc.

Medium temperature: Select the appropriate valve version based on the medium temperature. The standard version has a medium temperature range of -30 ° C to+170 ° C, while the special version can reach -100 ° C to+220 ° C.

3、 Determine the temperature and pressure range

Temperature range: Select the valve version according to the temperature requirements of the application scenario to ensure that the valve can operate normally within the required temperature range.

Pressure rating: The 7010 series angle seat valve offers pressure ratings such as PN16 and PN40, with pressures of 232psi and 580psi in imperial units. The appropriate pressure rating should be selected according to the system pressure requirements.

4、 Selection Example (Quick Comparison)

Scenario: Pharmaceutical CIP system, medium is 80 ℃ cleaning solution, pressure is 6bar, DN25, sanitary grade

Selection result: 7010-DN25, electrolytic polished stainless steel, three clamp connection, pneumatic normally closed, limit switch+manual override, oil-free+TA Luft seal
