Stainless Steel Hygienic Thread Safety Valve for Liquid Control
Our state-of-the-art safety valve is meticulously designed to maintain the set pressure within your system, acting as a vigilant guardian of safety. The sanitary safety valve provides crucial protection, ensuring the system operates smoothly without the risk of accidents due to excessive pressure build-up.
Product Description
Introducing our Overflow Safety Valve with Premium Stainless Steel Material: a robust and reliable solution designed to maintain the optimal pressure balance within your system. This valve plays a crucial role in safeguarding your system by automatically opening whenever the system pressure surpasses the pre-set threshold, effectively preventing any potential overpressure scenarios. Commonly referred to as a pressure relief or pressure release valve, it is meticulously calibrated to a specific pressure before dispatch, ensuring seamless integration and functionality upon installation. For enhanced monitoring, consider installing a pressure gauge before the valve's inlet. In regular operation, the valve remains securely closed, only activating when the pipeline pressure exceeds the designated limit, allowing for immediate pressure reduction and system stabilization. Additionally, our valve is versatile, featuring an optional handle for partial manual operation, ideal for spot cleaning processes where uninterrupted flow of cleaning product is required. Experience exceptional performance and peace of mind with this meticulously engineered component from Wenzhou Joneng Valves Co., Limited.
Working Principle
This Overflow Safety Valve, crafted with Premium Stainless Steel Material by Wenzhou Joneng Valves Co., Limited, operates as a self-regulating marvel. It ingeniously utilizes the pressure of the medium to perform its crucial function. By meticulously calibrating a specific pressure using the adjustable compression spring of the regulating cover and lock nut, it sets a maximum safe pressure benchmark. This threshold is essential to safeguard pipeline equipment from potential harm. When the pipeline pressure surpasses this pre-set limit, the valve seat instinctively opens, allowing the medium to be discharged, thereby releasing the pressure within the pipeline system. This timely intervention ensures the protection and longevity of both the pipeline and its associated equipment. As the pressure within the pipeline gracefully returns to its normal levels, the valve seat is automatically coerced back into its original position, culminating in the seamless closure of the valve. This entire process epitomizes the valve's ability to autonomously maintain equilibrium within the system, ensuring peace of mind and operational safety.
