Trapped Pressure Unloader Valve Mechanism:

• The General Pump ZH288 Trapped Pressure Unloader Valve operates using a straightforward trapped pressure unloader mechanism.
• Upon trigger release, the system builds pressure until it surpasses the spring resistance, causing the ball to move away from the bypass seat. This allows water to circulate at a minimal pressure level.
• The inlet check valve, then, traps pressure within the line to ensure consistent operation without the concern of pressure bleed-off, which might otherwise lead to cycling issues.
• It offers reliable high-pressure mode bypassing, as recommended for certain unloader models.
