Industrial Pneumatic Ball Valves

Pneumatic Thread Ball Valve

Designed for compact footprints, this valve features standard NPT or BSPT threaded ends for rapid, weld-free installation. It serves as a highly cost-effective, high-speed automated solution for general utility lines, cooling water, and compressed air networks.

Pneumatic Flange Ball Valve

Built with integral flanged ends (ANSI/DIN/JIS) to withstand heavy pipeline vibrations and mechanical stress. This robust air-actuated valve ensures maximum stability and secure, leak-tight connections in large-scale petrochemical and municipal fluid systems.

Pneumatic Sanitary Ball Valve

Manufactured from highly polished stainless steel with Tri-clamp ends and FDA-approved cavity-filled seals to meet strict hygiene standards. It delivers lightning-fast, sterile flow control specifically engineered for the food, beverage, and pharmaceutical industries.

Pneumatic Plastic Ball Valve

A lightweight, non-scaling automated valve crafted from durable UPVC, CPVC, or PP materials. It offers excellent resistance to mild corrosives, making it the most economical pneumatic choice for agricultural irrigation, wastewater treatment, and basic chemical handling.

Pneumatic Fluorine-lined Ball Valve

Fully lined with premium PTFE or PFA to provide absolute resistance against highly aggressive, volatile chemical media. It is the ultimate fail-safe isolation valve for demanding chemical processing, chlor-alkali plants, and hazardous acid transport.

Pneumatic High Pressure Ball Valve

Constructed from heavy-duty forged steel with reinforced internal components to endure extreme hydraulic surges and intense pressure drops. This rugged valve is designed for severe-service applications in oil extraction, gas pipelines, and heavy hydraulic machinery.

Pneumatic Heating Jacket Ball Valve

Engineered with a specialized thermal jacket that circulates steam or hot oil around the valve body to prevent media solidification. It is the critical automated solution for safely handling highly viscous fluids such as asphalt, liquid sulfur, resins, and chocolate.

Pneumatic V Port Segmented Ball Valve

Featuring a precision-engineered V-notch (30°, 60°, or 90°) and a powerful shearing action, this valve provides highly accurate proportional flow regulation. Paired with an electro-pneumatic positioner, it excels at modulating fibrous media, pulp, and abrasive slurries.

Pneumatic Actuators (AT & AW Series)

Engineered to power our automated solutions, we offer the AT Series (Rack-and-Pinion) for compact, high-cycle constant torque, and the heavy-duty AW Series (Scotch Yoke) for maximum breakaway power. Featuring standard NAMUR mounting, they perfectly match the exact torque demands of any standard, high-pressure, or large-diameter pipeline.

Need Custom Actuation?

Beyond our standard series, we provide custom actuator sizing, mounting bracket manufacturing, and specialized control signals (Modbus, Profibus) tailored to your exact DCS requirements.

Flow Path & Valve Structure

Specify flow path requirements (2-Way standard shut-off, or 3-Way T-Port / L-Port for 120°/180° diverting), body construction (1-piece, 2-piece, 3-piece, or V-port segmented for modulating control), and indicate if specialized configurations like a heating jacket are required based on your media viscosity and flow characteristics.

Connection Type & Size

Define nominal pipe size (DN15-DN300 / 1/2"-12") and standard end connections: Female Thread (NPT/BSPT), Flange (ANSI/DIN/JIS), Tri-Clamp, or Socket Weld.

Body & Seat Materials

Select body materials (SS304, SS316L, WCB Carbon Steel, UPVC) and soft or metal seats (PTFE, PEEK, Metal-to-Metal) strictly compatible with your process medium.

Operating Temperature

Provide working temperature ranges (-40°C to +350°C+) to determine if standard PTFE seats, high-temp PEEK, or high-performance metal seats are required.

Pipeline Working Pressure

Specify system pressure ratings (PN16-PN100 / Class 150-600) to verify valve body rating and calculate the exact breakaway torque for accurate actuator matching.

Actuator Series & Action Type

Select the actuator mechanism (AT Series Rack-and-Pinion for constant torque/fast cycles, or AW Series Scotch Yoke for high-torque heavy-duty needs) and choose your actuation mode: Double-Acting or Spring-Return (Fail-Safe).

Pneumatic Accessories & Control

Select required field accessories: Solenoid valves (AC220V/DC24V), limit switch boxes for position feedback, air filter regulators (FRL), or electro-pneumatic positioners (4-20mA).

High-Speed Actuation & Cycling

Driven by compressed air, our pneumatic actuators deliver ultra-fast response times (often under one second) and are built to endure millions of high-frequency cycles without performance degradation.

Inherent Explosion-Proof Safety

Unlike electric units, pneumatic actuators operate purely on mechanical air pressure, eliminating the risk of electrical sparks. This makes them the ultimate choice for highly flammable, ATEX-rated, and hazardous zones.

Fail-Safe Reliability

Plant emergencies demand immediate action. Our spring-return (single-acting) configurations guarantee that upon any loss of air supply or power, the valve will automatically revert to a designated safe position (normally open or normally closed) to prevent pipeline disasters.

Comprehensive Pipeline Adaptability

We manufacture pneumatic solutions for any fluid challenge. Whether your pipeline requires high-pressure or flange designs for refining, plastic or fluorine-lined bodies for severe acids, or sanitary finishes for hygiene. From heating jacket configurations for viscous media and V-port segmented balls for precise modulation, to compact threaded ends for utility lines—DELCO perfectly matches your specs.

Rigorous Testing & Global Compliance

Every valve-actuator assembly undergoes 100% hydrostatic and pneumatic seat testing per API 598 / ISO 5208 to certify ANSI Class VI zero leakage before dispatch. We provide full EN 10204 3.1 material traceability, CE compliance, and support international distributors with flexible OEM private labeling, neutral packaging, and reliable project lead times.

Expert Air-Supply & Torque Matching

A mismatched actuator leads to valve failure. Our factory engineers meticulously calculate torque requirements against your facility's available air supply pressure (typically 4-8 bar), ensuring the actuator is perfectly sized with a standard 30% safety margin.
