        A Guide to the ZZY Self-operated Pressure Control Valve

        In industrial fluid and gas systems, maintaining stable pressure is paramount for operational safety, efficiency, and quality. The ZZY Self-operated Pressure Control Valve offers an innovative and reliable solution by providing precise pressure regulation without the need for any external power source. By harnessing the energy of the controlled medium itself, this valve delivers autonomous, dependable performance for a wide range of applications.

        Core Principle: Energy-Independent Operation

        The defining feature of the ZZY valve is its self-contained design. It operates by taking the energy from the controlled medium—be it gas, liquid, or steam—and using it as its source of power. This internal energy is directed to an actuator, which controls the valve core’s position. By precisely adjusting the flow area, the valve effectively alters the flow rate to ensure that the upstream (or downstream) pressure remains stable at the desired setpoint. This intelligent, self-powering mechanism eliminates the need for electrical or pneumatic auxiliary power, reducing operational complexity and cost.

        This series is available in two distinct configurations to meet specific system requirements:

        • Pressure Regulators: For controlling and stabilizing downstream pressure.

        • Pressure Relief: For controlling and stabilizing upstream pressure.

        Key Features and Benefits

        The ZZY Self-operated Pressure Control Valve is engineered for superior performance in demanding industrial environments.

        • High Precision and Sensitivity: The valve demonstrates highly sensitive action, reacting swiftly to pressure changes to maintain stability.

        • Excellent Sealing Performance: It is designed for good sealing, which minimizes leakage and improves system efficiency.

        • Stable Pressure Control: Users benefit from small pressure fluctuation, ensuring consistent and predictable system operation.

        Technical Specifications

        To accommodate diverse industrial needs, the valve is available with a variety of specifications.

        • Product Type: Self-operated Pressure Control Valve.

        • Body Size: Ranges from DN15 to DN450 (1/2″ – 18″).

        • Pressure Ratings: Supports a wide range, including PN1.6, 4.0, 6.4, up to 32.0, and ANSI Class 150, 300, 600, up to 1500.

        • Connection Options: Available in flanged (RF) and welding (SW, BW) types.

        • Body & Bonnet Materials: Constructed from durable materials like WCB, CF8, CF8M, CF3, and CF3M.

        • Operating Temperature:

          • Standard Type: .

          • Middle Temperature Type (with condenser): Suitable for temperatures up to .

        • Flow Characteristics: Features a Quick Open design.

        • Regulating Accuracy: Offers a regulating accuracy of ±5%.

        Broad Industrial Applications

        Thanks to its robust design and reliable performance, this valve is widely used for the automatic control of pressure for gas, liquid, and steam mediums across various industrial devices. Whether for pressure reduction and stabilization or for pressure relief functions, the ZZY valve is an ideal choice for ensuring process integrity.

        FAQs

        How does the Self-operated Pressure Control Valve work without electricity?

        It does not require external energy. Instead, it cleverly utilizes the inherent energy of the controlled medium (gas, liquid, or steam) as its own power source to actuate the valve and regulate pressure.

        What is the maximum operating temperature this valve can handle?

        The standard model is suitable for temperatures up to 80°C. For higher temperature applications, a middle temperature version equipped with a condenser can operate at temperatures up to 350°C.

        What are the two main types of this valve?

        This valve is available in two primary configurations: the pressure regulator type, which controls downstream pressure, and the pressure relief type, which controls upstream pressure.

        What is the control accuracy of the ZZY valve?

        The valve is designed to provide a regulating accuracy of ±5%, ensuring stable and reliable pressure management.

        What materials are used for the valve body?

        The valve body and bonnet are available in a variety of materials to suit different media and conditions, including WCB, CF8, CF8M, CF3, and CF3M.
