Adjustable pressure handle: The Hydraulic Pressure Switch Pressure Relay has a smooth adjustable pressure handle. Turning right increases pressure and turning left decreases it. It works with a pressure gauge for accurate regulation and features clear scale markings for easy reading. Oil connection route: Senses pressure through an oil connection route with a default internal thread of RC1/4. This provides straightforward mounting to compatible hydraulic systems. precision hydraulic pressure detection: Delivers accurate measurement and control of hydraulic systems thanks to precision hydraulic oil pressure detection. Material and seals: Constructed from cast iron and equipped with imported oil seals that resist pressures and temperatures without leaking oil. Benefits and applications: Precise control: Easy, reliable adjustment and monitoring of hydraulic pressure to improve system performance and safety. Robust construction: Cast iron body and quality seals ensure durability in demanding environments. Compatible connections: RC1/4 internal thread supports common hydraulic installations. Use scenarios: In hydraulic presses or forming equipment to regulate clamping pressure with realtime gauge reference. In hydraulic power units or testing rigs requiring stable, adjustable pressure with clear scale feedback. In industrial machinery that operates under pressure and temperature, where leak prevention and accurate detection are critical.
