HySecurity MX000222, VALVE CARTRIDGE, MANUAL BYPASS
HySecurity MX000222 is a manual bypass / quick stop valve cartridge for select HySecurity StrongArm 36 / HTG 320-8 hydraulic barrier gate operator applications. HySecurity StrongArm parts documentation lists MX000222 as "Valve, Manual Bypass/Quick Stop" for StrongArm 36 models.
Current listings describe MX000222 as a manual bypass valve, 8 GPM, for StrongArm 36 / HTG 320-8. Some listings also note use as a direction valve in HydraSupply XL. Because hydraulic valve fitment depends on the pump pack layout, valve cavity, hydraulic function, operator model, and service configuration, MX000222 should be selected only after confirming the original valve location and HySecurity parts diagram.
What This Manual Bypass / Quick Stop Valve Does
The manual bypass / quick stop valve is part of the StrongArm 36 hydraulic circuit. In the approved hydraulic system, it is associated with manual bypass and quick-stop hydraulic control functions used by the pump pack and arm-control circuit.
A stuck, leaking, contaminated, damaged, incorrectly installed, or wrong manual bypass / quick stop valve can contribute to drifting, poor holding, poor hydraulic response, difficulty manually moving the arm, slow movement, pressure problems, inconsistent arm control, or improper quick-stop behavior. Similar symptoms can also be caused by brake valve issues, check valve leakage, relief valve problems, cylinder bypass, hose leaks, contaminated fluid, pump wear, valve coil problems, arm binding, or incorrect counterweight balance.
Compatible With
Use HySecurity MX000222 only where the operator parts diagram, original valve, or HySecurity documentation confirms this part number.
- Select HySecurity StrongArm 36 hydraulic barrier gate operator applications where MX000222 is listed as the manual bypass / quick stop valve.
- Select HySecurity HTG 320-8 applications where the parts diagram lists MX000222.
- StrongArm 36 pump pack repairs where the original manual bypass / quick stop valve is marked, listed, or cross-referenced as HySecurity MX000222.
- Applications where the 8 GPM valve rating, valve cartridge, valve cavity, manual bypass / quick stop function, and pump pack configuration match the HySecurity parts diagram.
- Select HydraSupply XL applications only where the parts diagram confirms MX000222 as the correct direction valve.
Important Compatibility Warning
MX000222 is listed for StrongArm 36 / HTG 320-8. It should not be treated as the same part as MX000230, which HySecurity lists as the manual bypass valve for StrongArm models except StrongArm 36. It should also not be confused with MX000231, which is the manual bypass flow control valve.
Hydraulic cartridges are circuit-specific. A valve with a similar appearance, description, flow rating, or thread size may not perform the same function. Installing the wrong valve can cause arm drift, poor stopping, hydraulic pressure problems, overheating, or unsafe barrier arm movement.

Technician Note
Before replacing MX000222, inspect the manual bypass / quick stop valve location, coil and wiring if applicable, hydraulic fluid condition, StrongArm 36 brake manifold, pump pack, brake valve, related check valves, relief valve, hoses, fittings, hydraulic cylinder, and arm balance. A barrier arm that drifts, drops, stops poorly, or will not hold is not always caused by this valve.
If the manual bypass / quick stop valve is contaminated, stuck, leaking, or not reseating correctly, the arm may move differently than expected. Contaminated fluid, damaged coils, hose debris, or valve-cavity damage can cause repeat problems if the surrounding hydraulic system is not corrected during service.
Before Ordering, Confirm
- The required part number is MX000222.
- The operator is a HySecurity StrongArm 36 / HTG 320-8 application where the parts diagram lists MX000222.
- The repair requires the manual bypass / quick stop valve, not the MX000230 manual bypass valve or MX000231 manual bypass flow control valve.
- The valve cavity, hydraulic circuit, valve function, flow rating, and pump pack layout match the original installation.
- The issue is not caused by the MX000185 quick stop valve coil, wiring, brake valve, check valves, relief valve, low fluid, contaminated fluid, leaking hoses, cylinder bypass, pump wear, arm binding, or incorrect counterweight balance.
- The package includes the expected valve cartridge and any required seals, O-rings, coil, fittings, or installation parts, or those parts are ordered separately.
- The operator has not been modified with non-standard pump pack, brake manifold, or hydraulic valve hardware.
- HydraSupply XL use is confirmed by the correct parts diagram if ordering this part for that application.
Installation and Service Notes
- Secure the barrier arm before servicing hydraulic valves or pump pack components.
- Do not work under an unsupported arm or counterweight-loaded arm assembly.
- Disconnect and secure operator power before servicing the pump pack area.
- Relieve hydraulic load according to the manufacturer's service procedure before removing hydraulic valves or fittings.
- Keep hydraulic ports, valve cavities, fittings, and hose ends clean during service.
- Do not swap valve locations, coils, or similar-looking hydraulic cartridges.
- After installation, confirm proper manual bypass operation and quick-stop behavior according to the operator service procedure.
- After service, check for leaks, proper arm hold, smooth travel, correct stopping behavior, proper limit operation, and all required safety devices.
Professional Advisory
StrongArm 36 hydraulic valve service should be handled by a qualified gate technician when the repair involves hydraulic pressure, manual bypass operation, quick-stop function, pump pack diagnosis, heavy barrier arms, counterweights, valve cavities, fluid contamination, hose routing, pressure-control valves, valve coils, or unknown prior modifications. Do not bypass limit controls, stop circuits, kill switches, hydraulic protections, overloads, controller protections, access control safety inputs, photo eyes, safety edges, or any required safety devices to keep the operator running.
