WanerF BT-04-3-30 – 1/2 Inch Threaded Hydraulic Relief Valve, Pressure Adjustment

✅ WanerF BT-04-3-30 is a mechanical hydraulic relief valve designed to control and limit pressure in hydraulic oil systems. It helps protect pumps, pipelines, cylinders and other hydraulic components from excessive pressure.

✅ The BT-04-3-30 features an approximately 1/2-inch connection, making it suitable for hydraulic oil lines used in industrial machinery. Its threaded design allows convenient installation directly into compatible hydraulic piping.

✅ The valve operates through a mechanical spring adjustment mechanism. The pressure setting can be adjusted according to the operating requirements of the hydraulic system.

✅ When system pressure reaches the preset value, the relief valve opens to discharge hydraulic oil and prevent further pressure increase. This provides an essential pressure protection function for hydraulic circuits.

✅ The reference pressure adjustment range can be approximately 20–250 kgf/cm², equivalent to around 2–24.5 MPa, depending on the actual configuration and application.
