Is the MRF HTC plastic pneumatic throttling and check valve, for actuator, HIGH-FLOWS series compatible with 1/8â³ and 1/4â³ actuator ports and rated for up to 10 bar?

Yes. The MRF HTC plastic pneumatic throttling and check valve, for actuator, HIGH-FLOWS series is available in sizes 1/8â³ and 1/4â³ and is rated for working pressures up to 10 bar. It is designed for high-flow filling and venting, mounts directly to actuator ports, features a plug connection for hose disassembly, adjustable flow via knob or screwdriver with locking nut, operates from -10Â°C to +50Â°C, and is made of plastic.

Can the MRF HTC plastic pneumatic throttling and check valve, for actuator, HIGH-FLOWS series handle bi-directional flow control for rapid fill and vent cycles?

Yes. The MRF HTC plastic pneumatic throttling and check valve, for actuator, HIGH-FLOWS series is designed for direct mounting in actuator connections and is recommended for high-flow applications during both filling and venting. Its built-in throttle and check function permits controlled flow in one direction and free or restricted flow in the opposite direction, enabling bi-directional flow control for rapid fill and vent cycles. Adjustable via a control knob or screwdriver (and lockable with a nut), available in 1/8â³ and 1/4â³, rated to 10 bar and -10Â°C to +50Â°C.

Q: How do I lock the adjustment on the MRF HTC plastic pneumatic throttling and check valve, for actuator, HIGH-FLOWS series to prevent tampering?

To lock the adjustment on the MRF HTC plastic pneumatic throttling and check valve, for actuator, HIGH-FLOWS series and prevent tampering, proceed as follows: 1. Set desired flow: adjust the control knob (or use a screwdriver in the adjustment slot) until the required flow/response is achieved during actuator fill or vent. 2. Secure with locking nut: once set, tighten the provided locking nut against the knob/body to mechanically fix the adjustment. Ensure the nut is fully engaged and snug to prevent rotation. 3. Verify seal and access: if additional tamper-resistance is required, apply a thread-locking compound rated for plastics (compatible with the valve material and operating temperature of -10Â°C to +50Â°C) between the knob and nut before final tightening, or fit a tamper-evident seal/wire through the nut if the design allows. 4. Re-check operation: cycle the actuator at working pressure (up to 10 bar) to confirm setting remains stable and there is no binding. 5. Maintenance note: for future readjustment, loosen the locking nut (and remove any compound or seal) before turning the knob. Follow these steps to lock the adjustment securely while maintaining safe operation and serviceability of the MRF HTC plastic pneumatic throttling and check valve, for actuator, HIGH-FLOWS series.
