Product Description
The ZZY type self-operating pressure regulating valves are marvels of engineering that effortlessly harness the energy of the controlled medium as their sole power source. These sophisticated valves employ an actuator to deftly maneuver the valve core position, dynamically altering the flow area. This ingenious mechanism thus fine-tunes the flow rate, ensuring a consistent and stable pressure either before or after the valve, all without the need for any external energy.
Featuring impressively sensitive operation and exceptional sealing capabilities, these valves exhibit minimal pressure fluctuations. They shine as indispensable components in the realm of automatic control, deftly managing pressure reduction and stabilization or pressure relief and stabilization. Their versatility makes them ideally suited for handling gas, liquid, and steam mediums across a diverse array of industrial equipment.
In the distinguished series produced by SNT Machinery (Qingdao) Co., Ltd., our products are meticulously categorized based on the valve core type into single-seat (P), sleeve (M), and double-seat (N) structures. Furthermore, they are designed with three distinct actuator types: diaphragm, piston, and bellows, catering to a wide spectrum of operational needs and preferences.
Operating Principle
When deployed for managing downstream pressure, the ZZYP-B type valves excel in their roles of pressure reduction and stabilization. Should the downstream pressure exceed the predetermined set value, the valve instinctively begins to close, ultimately shutting off. Conversely, when the downstream pressure falls below the desired set value, the valve opens to make amends, effortlessly balancing the pressure.
For the task of controlling upstream pressure, the ZZYP-K type valves stand out with their adept skills in safety pressure relief and stabilization. As the upstream pressure surpasses the designated set value, the valve strategically opens and fully opens to alleviate the pressure. When the upstream pressure dips beneath the set threshold, the valve discreetly remains closed, ensuring stability.
The pioneering ZZYP-II series nitrogen sealing device, a self-operating micro-pressure control system, is a testament to the ingenuity and independence of our company's development efforts. It plays a crucial role in maintaining a stable pressure of protective gas, typically nitrogen, atop storage tanks. This innovative system prevents direct exposure of the tank contents to air, thereby safeguarding against material evaporation and oxidation, while guaranteeing container safety.Perfectly suited for gas sealing protection systems of extensive storage tanks, this product exemplifies energy efficiency and operational sensitivity. Its reliable performance and simplicity in operation and maintenance make it a popular choice in industries such as petroleum and chemical engineering, where precision and safety are paramount.
Revolutionizing convenience, this device requires no external energy sources, operating efficiently without electricity or gas. Its energy-saving nature and cost-effectiveness make it an incredibly practical choice for modern industrial applications. The nitrogen sealing device is a model of ease, allowing for straightforward nitrogen supply and vent pressure setting. It seamlessly operates under continuous production conditions, thanks to its large effective area pressure detection diaphragm and low spring stiffness. The device's sensitive operation and smooth functionality ensure flawless performance time and again.
To uphold the utmost safety of the storage tank, a breather valve is mandatory at the tank's apex. Serving a singular safety purpose, this valve circumvents the frequent and wear-inducing opening and closing associated with traditional nitrogen supply and vent valves, thereby significantly enhancing the longevity and reliability of the nitrogen sealing devices.Test and Detection Equipment
