Q1: What is the primary appliion of this specific valve?
A: This is a high-flow, manually adjustable throttle valve. Its primary appliion is to provide precise speed control for hydraulic cylinders or motors in one direction within medium to high flow hydraulic systems, while allowing free return flow via its integrated check valve. The NG22 size makes it suitable for larger actuators.
Q2: What is the significance of the "NG22" size in the model?
A: NG22 is the nominal size designation, corresponding to a CETOP 8 interface. It indies a larger valve with larger internal flow paths and port connections, designed to handle significantly higher flow rates (approximately 200 L/min) compared to smaller sizes like NG10 or NG16, with lower pressure losses.
Q3: What is the maximum allowable system pressure?
A: The valve is rated for a maximum operating pressure of 315 bar.
Q4: How is the flow setting adjusted and secured against vibration?
A: The flow rate is adjusted by turning the handwheel, which moves a precision spindle to change the orifice opening. To prevent the setting from shifting due to machine vibration, the valve is equipped with a separate locking nut. After setting the desired flow, this nut must be tightened against the valve body to lock the spindle in place.
Q5: What are the designated flow paths for the throttle and check functions?
A:
Throttling Path: Flow is metered (restricted) when it passes from Port 1 (P, inlet) to Port 2 (A, outlet).
Free-Flow Path: The integrated check valve opens to allow unrestricted flow from Port 2 (A) back to Port 1 (P).
Q6: What is the expected maximum flow capacity for this valve?
A: For the NG22 size, the typical maximum flow capacity is approximately 200 liters per minute. The actual achievable flow at any given handwheel setting is dependent on the pressure drop across the valve. For accurate sizing, the manufacturer's flow vs. pressure drop (Δp-Q) characteristic curves must be consulted.
