Festo Pneumatic Regulator G 1/4 Female MS4-LR-1/4-D5-AS

Festo MS4-LR-1/4-D5-AS pneumatic regulator with G 1/4 female inlet and outlet connections is engineered for high-performance pressure control in pneumatic systems. It features a directly actuated diaphragm regulator design that maintains constant output pressure, preventing system overload due to supply pressure fluctuations. This reliable regulator is suitable for use with compressed air and inert gases, including lubricated media, ensuring broad application versatility.

The unit incorporates a lockable rotary knob, which secures the set pressure against unauthorized tampering, and includes an integrated secondary exhaust to safely relieve excess pressure. The durable construction combines a die-cast aluminium body with polyamide and polyoxymethylene components, ensuring resistance to shock, vibration, and harsh industrial environments.

With an operating pressure maximum of 20 bar and operating temperature ranging from -10°C to +60°C, this regulator is adaptable for demanding environments such as drinks manufacturing, aerospace engineering, and pharmaceutical production. The regulator supports various mounting styles including in-line, front-panel, and accessory-based installations to suit different system configurations.

Certified according to ISO 8573-1:2010 (7:4:4), RoHS compliant, CE marked under EU Explosion Protection Directive ATEX, and UL listed (cULus), the Festo MS4-LR-1/4-D5-AS meets stringent safety and quality standards for industrial pneumatic regulation.
