YR_Pneumatic rotary actuator for the automation process

Product catalog summary

Technical Characteristics
Pneumatic actuators are designed with a NAMUR interface for pneumatic connections, adhering to VDI/VDE 3845 standards. They feature ISO 5211 and DIN 3337 compliant valve connections. Single acting actuators have 2-6 spring configurations. Operational temperature ranges from -20° to 80°C, using filtered air or neutral gases. Pressure ranges are 3 to 8 bar for single acting and 2 to 8 bar for double acting actuators, with a maximum of 10 bar. Rotation is adjustable between 0 - 90° ± 3°.

Constructive Characteristics
The body is made of hard anodized aluminum, with die-cast aluminum pistons and end caps. Piston bearings are acetalic resin, and the pinion is nickel-plated steel. Seals are nitrile rubber, and screws and nuts are stainless steel.

Codification Key
The YR2 series represents pneumatic actuators for process automation, available in sizes from 32 mm to 250 mm, with double acting (DA0) and single acting (S12) versions.

Performance Data
Details include weight, opening and closing times at 5.6 bar, air consumption, and torque output for models YR200 to YR210.

Brass Ball Valves PN 40
These valves have a full bore design, anti-blow out stem, and top-flange for direct mounting. Made from hot pressed brass, they operate from -20° to 120°C with a working pressure of PN 16 to PN 40. The rotary angle is 90°.

SS 316 Ball Valves
Available in two and three-piece configurations, featuring an anti-blow out stem and anti-static device. Constructed from ASTM-A351-CF8M, they operate from -20° to 230°C with a maximum pressure of PN 64.

Three-Way Ball Valves
SS 316 valves with a reduced bore and 'L' type configuration, sharing construction and operational characteristics with two and three-piece valves.

Specifications
Technical specifications for AISI 304 stainless steel and three-way ball valves made from SS 316 and brass. Operating temperature range is -20°C to 190°C, handling fluids like air, water, and chemicals. Working pressure is PN 63 max, with thread ends conforming to various standards. Rotary angle is 90°.

Valve Types and Features
Describes SS 316 and brass "L" type three-way ball valves, available with lever or pneumatic actuators. Features include reduced bore, anti-blowout stem, antistatic device, and top-flange for direct mounting.

Actuator Sizing
Specified with a minimum air supply of 5.5 bar and a maximum ΔP valve of 16 bar. Details both double acting and single acting configurations.

Construction and Materials
Includes body, end cap, ball, seat ring, body seal, stem, thrust washer, O-ring, gland packing, and gland ring nut. Materials include nickel-plated OT 58, P.T.F.E., VITON, and chromium-plated OT 58.

Operating Instructions
Instructions for changing outlet combinations involve removing the lever, adjusting the stem, and resetting the lever. Includes a codification key for identifying valve series, size, and version.
