Key features: pneumatic actuation for remote/safer control, compact monoblock construction for reduced leak paths and easier installation, and a robust pressure rating up to 315 bar for demanding mobile equipment. Performance range: rated flow 160 L/min (42.2 US gpm); operating viscosity 12–400 mm²/s to handle cold starts and varying oil grades; ambient temperature -40°C to +80°C for outdoor and all-season use. Typical applications: on/off and directional control of hydraulic functions on forklifts/telehandlers, loaders, aerial platforms, dumpers, and agricultural implements where pneumatic signal control is preferred. Supply options: manufacturer direct support for OEM/ODM, custom configurations, private label, bulk wholesale, and distributor/agent cooperation for global markets.
