CONTROL BALL VALVES FOR SALE

Control ball valves are a specialized type of ball valve designed for precise regulation of flow in various industrial processes. Unlike standard ball valves, which are primarily used for simple on/off control, control ball valves are engineered to throttle or modulate flow rates accurately. This makes them indispensable in applications where maintaining specific flow conditions is crucial, such as in HVAC systems, chemical processing, power generation, and oil and gas industries. Their ability to handle high pressures, temperatures, and corrosive fluids makes them ideal for demanding environments.

THE COMPONENTS OF A CONTROL BALL VALVE

Control ball valves share the same fundamental components as standard ball valves, but with some key modifications for enhanced precision and control:

• Body: The housing that contains the valve's internal components, typically made of durable materials like stainless steel or carbon steel.

• Ball: A spherical component with a precisely machined bore or port that regulates the flow rate. The shape of the bore or port can be customized for specific flow characteristics.

• Stem: A shaft that connects the ball to the actuator, allowing for precise positioning and control.

• Seats: Rings or discs that form a tight seal around the ball when the valve is closed.

• Packing: Sealing material around the stem to prevent leakage.

• Actuator: An electric, pneumatic, or hydraulic device that controls the valve's position based on input signals. The actuator is the key component that differentiates control ball valves from standard ball valves. It receives signals from a control system or operator and translates them into precise movements of the ball, enabling accurate flow regulation.

• Positioner (Optional): An additional device that provides feedback control to ensure accurate positioning of the ball. It measures the actual valve position and compares it to the desired position, making adjustments as needed to maintain precise control.

CONTROL BALL VALVE BRANDS WE OFFER

To ensure you get a quality ball valve with a long life, we partnered with quality brands such as Belimo, Honeywell, KMC, and others.

Honeywell control ball valves are designed for precise control and reliable operation in HVAC systems. Their VBN series includes both two-way and three-way control ball valves, suitable for hot and chilled water applications. These valves come in various sizes and configurations, with options for both threaded and flanged connections. Honeywell ball valves are known for their durability, tight shutoff, and compatibility with various actuators, making them a versatile choice for a wide range of HVAC applications.

KMC Controls ball valves feature the VFB Series, which also includes two-way and three-way control valves. These valves come with options for NPT or sweat connections, and are known for their tight shutoff and durability. KMC ball valves are often paired with KMC actuators for precise control in HVAC systems.

Belimo control ball valves are designed for flow regulation and efficient operation in heating, cooling, and ventilation systems. These valves are engineered with advanced technology, ensuring accurate modulation of flow rates and optimal energy efficiency. Built with high-quality materials, Belimo control ball valves are durable, reliable, and come in various configurations to meet diverse requirements. They seamlessly integrate with Belimo actuators for automated control and precise positioning, making them an ideal choice for optimizing HVAC performance and reducing energy consumption.

CONTROL BALL VALVE TYPES FOR SALE ON OUR WEBSITE

Our ball valves come in several different types:

• Characterized Control Valve (CCV): Characterized Control Valves (CCVs) are a specific type of control ball valve designed for precise flow regulation. They feature a modified ball with a unique opening shape that provides a predictable and repeatable flow characteristic curve. This allows for accurate control over a wide range of flow rates, making CCVs ideal for applications where precise control and repeatability are crucial. These valves are commonly used in HVAC systems, chemical processing, and industrial automation, where maintaining specific flow conditions is essential for optimal performance.

• Zone Valve: Zone valves are a specialized type of control valve used in hydronic heating and cooling systems. They are designed to control the flow of water to specific zones or areas of a building, allowing for individual temperature control in each zone. Zone valves typically operate in an on/off mode, opening or closing to direct water flow to a particular zone as needed. They are often controlled by thermostats or other control systems, enabling automatic temperature regulation and increased energy efficiency. Zone valves are essential for optimizing comfort and reducing energy consumption in multi-zone HVAC systems.

Control ball valves offer a wide range of options, tailored to meet specific needs and application requirements. Their diverse characteristics enable precise flow control and reliable operation in various industrial settings. Some key differentiating factors include housing, size, actuator type, torque, voltage, spring return, and others.

CONTROL BALL VALVES BY HOUSING

One crucial characteristic that differentiates control ball valves is their housing, which provides protection and ensures reliable operation in diverse environments. NEMA (National Electrical Manufacturers Association) ratings classify housing and enclosures based on their ability to withstand environmental conditions. Here's a breakdown of control ball valve types based on their NEMA housing ratings:

• NEMA 1: Designed for indoor use, protecting against accidental contact and falling dirt. Suitable for controlled environments with minimal exposure to moisture or dust. 

• NEMA 2: Similar to NEMA 1, with additional protection against dripping and light splashing of water. Commonly used in indoor locations where occasional moisture is present, such as pump rooms or boiler rooms. 

• NEMA 4: Provides protection against water ingress from hose-directed sprays and rain. Suitable for outdoor or washdown environments where moderate water exposure is expected. 

• NEMA 4X: Similar to NEMA 4, with additional protection against corrosion.

• NEMA 4H: Combines the features of NEMA 4 with resistance to hose-directed water and corrosion. 

• NEMA 4XH: Offers the highest level of protection, combining NEMA 4X's corrosion resistance with NEMA 4's water ingress protection.

CONTROL BALL VALVES BY SIZE

Control ball valves are available in a wide range of sizes, ensuring a proper fit for various applications and flow demands:

• Small (1/4" - 3/4"): For residential plumbing, smaller HVAC systems, and instrumentation.

• Medium (1" - 2"): Commonly used in residential and commercial plumbing, HVAC systems, and industrial applications.

• Large (2 1/2" and above): For large-scale industrial applications with high flow rates, such as pipelines and chemical processing.
