The thermal release valve protects pressure washer pumps operating within a safe temperature range to prevent overheating. When the water temperature exceeds 145°C, the pump seals can fail. The thermal release valve opens to release the hot water and allow the Cold water enters the pump. This ensures it continues to operate at a safe temperature. If the pump has already overheated, the thermal relief valve must be closed. Made of brass. Maximum load: Pump inlet pressure: 200 psi. Satisfaction: Prompt response within 10 hours.
