        DELCO Electric PVC Butterfly Valve: The Ultimate Solution for Corrosive Fluid Control

        In applications where metal valves falter due to corrosion, the DELCO Electric PVC Butterfly Valve stands out as a superior, cost-effective, and reliable solution. This valve assembly is engineered specifically for handling aggressive and corrosive media, combining a robust plastic butterfly valve with a versatile, integrated electric actuator. Its lightweight and highly corrosion-resistant properties make it an indispensable component in a multitude of industries, offering unparalleled performance where traditional materials cannot compete. Whether you need simple on/off isolation or precise flow modulation, this automated valve package provides a durable and efficient answer to your fluid control challenges.

        Core Advantages & Features

        Exceptional Corrosion Resistance

        The primary advantage of this valve lies in its construction from advanced thermoplastic materials. The valve body and disc are available in a range of plastics to suit specific chemical compatibility needs, including UPVC (Unplasticized Polyvinyl Chloride), CPVC (Chlorinated Polyvinyl Chloride), RPP (Reinforced Polypropylene), and PVDF (Polyvinylidene Fluoride). This material selection makes the valve immune to rust and resistant to a wide array of acids, bases, chemical solutions, saltwater, and seawater. This inherent resistance eliminates the need for expensive exotic alloys, providing a long-lasting and economical solution for aggressive fluid handling. The design is complemented by durable seating materials like NBR and EPDM, ensuring a tight seal and reliable performance.

        High-Performance Electric Actuator for Unmatched Reliability

        The valve is paired with a powerful DELCO electric actuator built for longevity and dependable performance. The actuator’s body is constructed from hard aluminum alloy, which is then treated with hard anodic oxidation and coated with polyester powder for exceptional corrosion resistance. It boasts a standard protection class of IP65, ensuring it is completely dust-tight and protected against water jets from any direction. Inside, a fully enclosed, cage-type motor delivers high torque from a compact size , while its F-grade insulation prevents overheating during demanding cycles. The actuator’s core is an accurate turbo-worm gear structure that is highly efficient, operates with low noise (max 50 decibels) , and provides a critical self-locking function to prevent reverse rotation, ensuring the valve maintains its set position without deviation.

        Reliable and Versatile Electric Actuator

        Automation is powered by a robust DELCO electric actuator designed for dependability and precision. The actuator housing is made of a hard aluminum alloy treated with anodic oxidation and a polyester powder coating, providing excellent durability and water-proof protection to an IP65 standard, with options for IP67/68. A fully enclosed, cage-type motor with F-grade insulation delivers high torque and prevents overheating. The precision turbo-worm gear structure is self-locking, preventing the valve from back-driving and ensuring it holds its position accurately with minimal noise. This actuator can be configured for various control schemes:

        • On/Off Type: For simple, two-position isolation to open or close a line.

        • Regulation (Modulating) Type: For precise flow control, this type accepts input signals like 4-20mA DC or 1-5V DC to accurately position the valve at any angle between 0° and 90°.

        User-Friendly Design for Easy Installation and Operation

        The valve assembly is designed for practicality and ease of use. The primary connection method is a quick-fitting clamp, which significantly reduces installation and maintenance time compared to traditional flanged or welded connections. Every actuator is equipped with a reliable and energy-saving manual override handle , allowing operators to position the valve during a power outage or for system setup. A clear visual position indicator is mounted directly on the center axis for at-a-glance confirmation of the valve’s status. Furthermore, the actuator’s mounting flange complies with the ISO 5211/DIN3337 standard, ensuring interoperability and simplifying the process of mounting or retrofitting.

        Lightweight and User-Friendly Design

        Compared to their metal counterparts, plastic butterfly valves are significantly lighter. This advantage simplifies installation, reducing the need for heavy lifting equipment and extensive pipe supports, which in turn lowers labor costs. The valve is engineered for user convenience, featuring a reliable manual override handle for operation during power loss or commissioning. An external, easy-to-read indicator displays the valve’s current position. Furthermore, the actuator’s mounting base complies with the ISO 5211/DIN3337 standard, ensuring easy and universal mounting on the valve.

        Engineered for Broad Applications

        The unique combination of chemical resistance, reliable automation, and lightweight design has led to the DELCO Electric PVC Butterfly Valve’s widespread adoption across numerous fields. Its quality and performance have been recognized by a large number of users in critical systems. It is a proven performer in pipeline systems for pure water, drinking water, drainage, and sewage, as well as highly demanding saltwater, seawater, and chemical solution systems.

        Why should I choose a PVC butterfly valve over a traditional metal one?

        A PVC butterfly valve is the superior choice for applications involving corrosive media like saltwater, acids, and various chemical solutions where metal valves would quickly degrade. They are also significantly lighter, making them easier and less expensive to install, and are often a more cost-effective solution than valves made from specialized corrosion-resistant metal alloys.

        What types of liquids and applications is this valve suitable for?

        This valve is ideal for a wide range of applications, including pure water and drinking water systems, drainage and sewage pipelines, saltwater and seawater systems (like in aquaculture or aquariums), and various acid-base and chemical solution systems. Its specific chemical compatibility depends on the selected body material (UPVC, CPVC, RPP, or PVDF).

        Can this valve be used to control the flow rate, or is it only for on/off service?

        Both options are available. The standard valve comes with an ON/OFF actuator for simple open and close operations. However, you can select a Regulation Type actuator, which accepts control signals (e.g., 4-20mA) to precisely position the valve anywhere between 0-90 degrees for accurate flow modulation and control.

        Is the electric actuator suitable for outdoor installation?

        Yes. The electric actuator has a standard protection class of IP65, which means it is dust-tight and protected against water jets. For long-term outdoor exposure to direct sunlight or heavy rain, placing the unit under an additional protective cover is recommended to maximize its service life. The ambient operating temperature range is -30°C to +60°C.

        What sizes are available for this valve?

        The DELCO Electric PVC Butterfly Valve is available in a wide range of sizes, from DN50 (2 inch) up to DN300 (12 inch), to accommodate various pipe system requirements.
