HySecurity MX000230, VALVE CARTRIDGE, MANUAL BYPASS
HySecurity MX000230 is a manual bypass valve cartridge for select HySecurity StrongArm hydraulic barrier gate operator applications. HySecurity StrongArm parts documentation lists MX000230 as "Valve, Manual Bypass" for StrongArm models all except StrongArm 36 / HTG 320-8.
The manual bypass valve is part of the StrongArm hydraulic pump pack circuit. It is used where the approved hydraulic design provides a manual bypass function for service or emergency manual movement procedures. Because hydraulic valve fitment depends on the pump pack layout, valve cavity, hydraulic function, operator model, and service configuration, MX000230 should be selected only after confirming the original valve location and HySecurity parts diagram.
What This Manual Bypass Valve Does
The manual bypass valve allows the hydraulic circuit to be manually bypassed where the operator design requires it. In a StrongArm system, this function is commonly associated with manual operation or hydraulic release procedures when the barrier arm must be moved under controlled service conditions.
A stuck, leaking, damaged, contaminated, incorrectly installed, or wrong manual bypass valve can cause drifting, failure to hold, poor hydraulic response, difficulty manually moving the arm, slow movement, pressure problems, or inconsistent arm control. Similar symptoms can also be caused by a brake valve issue, check valve leakage, relief valve problem, cylinder bypass, hose leaks, contaminated fluid, pump wear, manual bypass flow-control adjustment issues, arm binding, or incorrect counterweight balance.
Compatible With
Use HySecurity MX000230 only where the operator parts diagram, original valve, or HySecurity documentation confirms this part number.
- Select HySecurity StrongArm hydraulic barrier gate operator applications where MX000230 is listed as the manual bypass valve.
- StrongArm models all except StrongArm 36 / HTG 320-8, where the parts diagram confirms MX000230.
- StrongArm 14F, StrongArm 20, StrongArm 28, and StrongArmDOT 28 pump pack applications where MX000230 is listed.
- StrongArm hydraulic pump pack repairs where the original manual bypass valve is marked, listed, or cross-referenced as HySecurity MX000230.
- Applications where the valve cartridge, valve cavity, manual bypass function, and pump pack configuration match the HySecurity parts diagram.
Important Compatibility Warning
MX000230 is not listed for StrongArm 36 / HTG 320-8 in the standard StrongArm parts documentation. StrongArm 36 uses a different manual bypass / quick stop valve reference, commonly listed as MX000222. Do not substitute MX000230 for MX000222 unless the current HySecurity parts diagram specifically confirms that change.
Do not order MX000230 based only on the words "manual bypass." HySecurity hydraulic systems use multiple bypass, check, relief, brake, and directional valves. Similar-looking hydraulic cartridges may have different functions, pressure behavior, cavities, seals, and flow characteristics.

Technician Note
Before replacing MX000230, inspect the manual bypass valve location, knob or actuator condition, hydraulic fluid condition, pump pack, manual bypass flow control valve, brake valve, related check valves, relief valve, hoses, fittings, hydraulic cylinder, and arm balance. A barrier arm that drifts or will not hold is not always caused by the manual bypass valve.
If the manual bypass valve has been left open, is contaminated, or does not reseat correctly, the arm may drift or move differently than expected. After service or manual operation, confirm the manual bypass valve is fully returned to its normal operating position according to the service procedure.
Before Ordering, Confirm
- The required part number is MX000230.
- The operator is a HySecurity StrongArm application where the parts diagram lists MX000230.
- The operator is not a StrongArm 36 / HTG 320-8 application requiring MX000222 unless the current parts diagram confirms otherwise.
- The repair requires the manual bypass valve cartridge, not the manual bypass flow control valve, brake valve, check valve, relief valve, or directional valve.
- The valve cavity, hydraulic circuit, knob or actuator style, and pump pack layout match the original installation.
- The hydraulic issue is not caused by low fluid, contaminated fluid, leaking hoses, cylinder bypass, pump wear, brake valve failure, bypass flow-control adjustment, arm binding, or incorrect counterweight balance.
- The package includes the expected valve cartridge and any required seals, O-rings, knob hardware, or installation parts, or those parts are ordered separately.
- The operator has not been modified with non-standard pump pack or hydraulic valve hardware.
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 or substitute similar-looking hydraulic cartridges.
- After installation, confirm the manual bypass valve returns fully to its normal operating position.
- After service, check for leaks, proper arm hold, smooth travel, correct stopping behavior, proper limit operation, and all required safety devices.
Professional Advisory
StrongArm hydraulic valve service should be handled by a qualified gate technician when the repair involves hydraulic pressure, manual bypass operation, pump pack diagnosis, heavy barrier arms, counterweights, valve cavities, fluid contamination, hose routing, pressure-control valves, 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.
Product Questions & Answers
What is HySecurity MX000230?
HySecurity MX000230 is a manual bypass valve cartridge for select HySecurity StrongArm hydraulic barrier gate operator applications.
What StrongArm models use MX000230?
HySecurity parts documentation lists MX000230 for StrongArm models all except StrongArm 36 / HTG 320-8. Use it only where the operator parts diagram confirms this part number.
No, not based on the standard StrongArm parts documentation. StrongArm 36 / HTG 320-8 commonly uses MX000222 manual bypass / quick stop valve instead.
Is MX000230 the same as MX000231?
No. MX000230 is the manual bypass valve cartridge. MX000231 is the related manual bypass flow control valve and should not be treated as the same part.
Can a bad manual bypass valve cause the arm to drift?
It may be involved, especially if the valve is leaking or not fully reseated, but arm drift can also be caused by brake valve issues, check valve leakage, cylinder bypass, hose leaks, contaminated fluid, pump wear, or incorrect arm balance.
Can I replace MX000230 with a generic manual bypass valve?
No, not unless HySecurity documentation confirms the exact hydraulic function, valve cavity, seal style, and circuit compatibility. Similar-looking hydraulic cartridges are not automatically interchangeable.
Should a technician replace this manual bypass valve?
Yes. A qualified gate technician is recommended because this repair can involve hydraulic pressure, valve-cavity fitment, fluid contamination, heavy barrier arms, and safety-critical gate operator movement.
