How does the STD and pneumatic soft-start valve, VAP 100 series SKILLAIRÂ® (without end plates), protect actuators during startup and what inlet pressure range is required?

The STD and pneumatic soft-start valve, VAP 100 series SKILLAIRÂ®, without end plates, protects actuators during startup by introducing supply air gradually to avoid sudden pressure spikes. The STD version opens automatically once the outlet pressure reaches about 50% of the inlet pressure, enabling a controlled build-up. The pneumatic control version allows restricted flow through an internal needle valve when no pilot signal is present; when an external pneumatic control signal is applied the valve overrides and opens to full cross-section for normal flow. Neither version vents the pneumatic system. Required inlet pressure: up to 15 bar (typical operation and flow rating given at 6 bar inlet, Îp = 1 bar, flow 2000 l/min). Operating temperature up to +50Â°C.

Can the STD and pneumatic soft-start valve, VAP 100 series SKILLAIRÂ®, without end plates, be used at temperatures above +50Â°C?

No. The STD and pneumatic soft-start valve, VAP 100 series SKILLAIRÂ®, without end plates, has a specified operating temperature up to +50Â°C. Using it at temperatures above +50Â°C would exceed the declared limits and is not recommended, as it may impair function, reliability and safety. For operation at higher temperatures, consult the manufacturer for suitable alternatives or special versions.

Q: What maintenance is recommended for the STD and pneumatic soft-start valve, VAP 100 series SKILLAIRÂ®, without end plates, to ensure reliable operation?

Recommended maintenance for the STD and pneumatic soft-start valve, VAP 100 series SKILLAIRÂ®, without end plates to ensure reliable operation: - Regular visual inspection (monthly): check for external damage, leaks at connections and threads, and proper actuator mounting. - Leak test (quarterly): verify no air leakage at inlet, outlet and control ports under working pressure. - Functional test (quarterly): confirm STD function - valve opens automatically when outlet â50% of inlet pressure - and pneumatic override provides full flow when actuated; ensure needle valve provides controlled flow without pilot pressure. - Clean ports and filters (every 6â12 months): remove debris from inlet/outlet and any inline filters to prevent clogging. - Lubrication (annually or per manufacturer spec): apply appropriate pneumatic lubricant to moving parts if recommended by SKILLAIR. - Pressure/temperature checks: ensure supply â¤15 bar and temperature â¤+50Â°C during operation. - Replace worn seals or damaged components immediately; verify flow (~2000 l/min at 6 bar, Îp=1 bar) after repairs. - Keep maintenance and test records; follow SKILLAIR detailed manual for part-specific intervals.

Additional information

Maximum operating temperature [°C]	50

Soft start valve, used for the safe introduction of air into the pneumatic system, protecting actuators from sudden pressure increases. STD valve: opens automatically when the outlet pressure reaches approximately 50% of the inlet pressure. Pneumatic control valve: without pilot pressure, air flows from the inlet connection to the outlet through a needle valve. Upon receiving an external control signal, pneumatic, the valve is overridden and air flows through the full cross-section of the valve. The valve does not vent the pneumatic system. Size: 100. Supply pressure: up to 15 bar. Operating temperature: up to +50°C. Flow: 2000 l/min (at an inlet pressure of 6 bar Δp = 1 bar).
