Product Description
ZZY type self-operating pressure regulating valves offer a revolution in energy efficiency. They uniquely harness the power of the controlled medium itself, eliminating the need for external energy. Through the introduction of an actuator, they dynamically manage the valve core position to vary the flow area, perfectly calibrating the flow rate to ensure constant pressure either before or after the valve.
These valves are engineered for precision, boasting sensitive operation, superior sealing, and minimal pressure fluctuation. Their versatility shines in the automatic regulation of pressure reduction and stabilization or pressure relief and stabilization across gas, liquid, and steam mediums, making them indispensable in diverse industrial equipment.
Our company's exceptional product line offers a variety of configurations to meet specific needs. Choose from single-seat (P), sleeve (M), and double-seat (N) designs, each based on the valve core type. For actuators, select from diaphragm, piston, or bellows types, ensuring you find the perfect fit for your requirements.
Operating Principle
For downstream pressure control (ZZYP-B type), these valves excel in pressure reduction and stabilization. Should the downstream pressure exceed your desired set value, the valve instinctively closes, ultimately sealing off the flow. When the pressure falls below the set value, it remains open, adeptly balancing the pressure.
For upstream pressure management (ZZYP-K type), these valves serve as a bastion of safety pressure relief and stabilization. When the upstream pressure surpasses the set value, the valve springs open, fully accommodating the excess. Conversely, it stays closed when the pressure is below the desired level, ensuring stability.
Introducing the ZZYP-II series nitrogen sealing device, a self-operating micro-pressure control marvel exclusively developed by our innovation-driven company. It's designed to keep the protective gas-typically nitrogen-at a steady pressure atop storage tanks, thereby shielding the contents from air contact, preventing evaporation, and oxidation, and ensuring paramount container safety.Ideally suited for the gas sealing protection of expansive storage tanks, this product is acclaimed for its energy-saving, sensitive, and reliable performance. Ease of operation and maintenance make it a staple in the petroleum and chemical engineering sectors, standing as an icon of efficiency and dependability.
With no dependence on external power sources, this device operates independently without the need for electricity or gas, embodying convenience, energy savings, and cost-effectiveness. The nitrogen sealing device facilitates seamless nitrogen supply and precise vent pressure adjustments, functioning effortlessly even during continuous production. Its pressure detection diaphragm boasts a large effective area, with a low-stiffness setting spring for sensitive operation and smooth device performance.
To uphold the safety integrity of storage tanks, a breather valve is a vital installation at the tank's apex. Serving a critical safety role, it prevents the wear and tear typical of frequent valve operations in conventional nitrogen sealing devices, safeguarding the longevity and reliability of the system.Test and Detection Equipment
