New Pneumatic AZBIL Control Valve and Electro-Pneumatic Positioner Spiraxsarco EP6SLS1-A and Masoneilan SVI2 SVI3

The Spirax Sarco EP6SLS1-A is a reliable electro-pneumatic positioner that converts a 4-20 mA control signal into precise pneumatic output for accurate valve positioning. Designed for single-acting linear actuators conforming to NAMUR, it ensures exact proportionality between input signal and valve stroke, with a rugged die-cast aluminum housing suitable for outdoor installation.

• Two-wire loop-powered design requiring only the 4-20 mA signal.
• High-precision control with low hysteresis and good repeatability.
• Built-in pressure gauge (standard on many configs) to monitor output air pressure.
• Weather-protected aluminum enclosure for reliable outdoor use.
• Easy mounting on linear actuators with optional kits (e.g., EY series).
• Adjustable action for direct or reverse signal response.
• Low steady-state air consumption for efficient operation.

Well-suited for modulating control of pneumatic control valves in steam systems, heating circuits, process lines, and industrial plants—particularly with Spirax Sarco actuators like PN9000, TN2000, or PNS series where accurate positioning improves efficiency and response.

Q: What actuators does it work with?
A: Any NAMUR-compatible linear or rotary pneumatic actuators; linear stroke 20–150 mm.

Q: Is it loop-powered?
A: Yes—two-wire, powered directly by the 4-20 mA signal.

Q: Can it be used outdoors?
A: Yes, with IP66 protection and treated aluminum housing.

Q: What's the air supply requirement?
A: Clean, dry air 1.4–7 bar per ISO 8573-1:2010 Class 3:3:2.

Q: Does it include a gauge?
A: Standard models often feature a supply/output pressure gauge.
