ASCO sarja 327C

Solenoid valve series 327C

New 327C generation: next-generation direct acting solenoid valve for process valve actuation applications
Improved power-to-flow ratio: higher flow with lower power consumption
Lower power requirement: reduces the need for additional power supplies and enables more coils to be powered by a single controller
Higher flow in the standard construction: reduces the need for booster valves
Over 3x faster response time in IS version without booster electronics
External test terminal: quick coil testing without opening the enclosure
Wider terminal access: easier access to the terminal block for faster commissioning
Fully rotatable coil with locking mechanism
Non-breathing design with enclosed core: protects internal parts from corrosive external environments
316L SS enclosure: superior protection in harsh environments, with temperature range up to -60…+90 °C depending on version
Pin terminal connection: reduces moisture ingress into the coil and improves service life
Emerson sealing technology: reduced wear, low friction and better protection against valve sticking
Two-layer dynamic seal: reduces the need for a heavy spring and helps prevent stem jamming
Broader option portfolio: standard, manual reset and intrinsically safe constructions within the same product family
Global standardization: global approvals and construction options reduce supply chain complexity and part variants

Intrinsically Safe construction for hazardous areas
No minimum operating pressure required – operates even at 0 bar differential pressure
Fast response time without booster electronics
Low power consumption, nominal power 0.5 W / min. 35 mA
316L stainless steel construction for demanding and corrosive environments
High-flow construction: Kv 0.3, Kv 0.45 in TP-NVR version
NAMUR direct-mount option available
Manual reset options: NVR and tamper-proof NVR
SIL 3 capable, Exida certified; not applicable for MS versions
Extensive ATEX / IECEx / UL / ULc approvals for intrinsically safe areas

High flow piloting with no minimum operating pressure required
Balanced poppet construction for high flow at minimum power levels
316 stainless steel construction available for highly corrosive atmospheres
Temporary connector option allows for quick and easy coil testing without opening the enclosure
Pin terminal connection reduces the risk of moisture ingress into coil, preventing corrosion and providing long life and reliability
Available in NAMUR direct-mount and manual-reset constructions. Tamper-proof and no-voltage release manual reset options provide added safety
Global approvals to simplify supply chain by enabling global standardization
The IS construction is designed for installation in intrinsically safe areas, with properly approved and sized current and voltage limiting barriers. It features no booster electronics, resulting in quick response times
