Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the valve holder seats and retains correctly within the valve assembly.
- Direct Drop-In Replacement — Engineered to match the mounting profile and dimensions of the original EM50445, allowing straightforward installation without modification.
- Broad Equipment Compatibility — Fits QP2TZ, QP3TZ, LS300GK, MVH308DZ, MVH408DZ, WTB-16, WTB-16PD, AR13H, AR13HA/HAR, and AR13HC models across multiple Multiquip equipment lines.
- Maintains Valve Integrity — A properly functioning valve holder keeps the valve element correctly positioned, preventing pressure loss, fluid bypass, and inconsistent flow performance.
- Fluid System Safety — In fuel and fluid-carrying systems, a failed or cracked valve holder can allow uncontrolled leakage; using the correct OEM part maintains system integrity and safe operation.
The valve holder is a retention component that locates and secures a valve element — such as a check valve or fuel valve — within its housing, keeping it properly aligned so it can open and close as intended. When the valve holder is cracked, worn, or missing, the valve can shift out of position, leading to pressure drop, fluid leakage, or a complete loss of flow control. Replacing a damaged valve holder with the correct OEM part restores proper valve seating and ensures the system operates as designed.
