The casing serves as the primary structural component of pneumatic push-pull valves, protecting internal mechanisms while withstanding mechanical and environmental stress. Most casings are fabricated from aluminium alloys or stainless steel, each offering distinct advantages.

Aluminium is favored for its lightweight nature, cost-effectiveness, and excellent strength-to-weight ratio, making it ideal for applications in the automotive and aerospace sectors where weight reduction is critical. Stainless steel, particularly grades 304 and 316, provides superior corrosion resistance and mechanical strength, making it the preferred choice in marine environments, food processing, and chemical plants exposed to moisture and aggressive substances.

For high-pressure or extreme-condition applications, materials such as brass and specialized alloys like Hastelloy are employed. These offer exceptional resilience under thermal cycling and mechanical load, ensuring long-term performance in demanding industrial settings.

Seals and Gaskets

Seals and gaskets are vital for maintaining airtight and leak-free operation in pneumatic systems. These components prevent pressure loss, contamination ingress, and premature wear of internal parts. The most commonly used materials include nitrile rubber (NBR), fluorocarbon elastomers (FKM/Viton®), and PTFE (Teflon®).

Nitrile rubber is widely used in general industrial applications due to its excellent resistance to oils, fuels, and abrasion, along with good elasticity. It performs reliably in moderate temperature ranges (-30°C to +100°C). For environments involving high temperatures or exposure to aggressive chemicals—such as solvents, acids, or chlorinated compounds—fluorocarbon seals are preferred, capable of withstanding temperatures up to 200°C and offering outstanding chemical stability.

PTFE gaskets provide near-universal chemical resistance and function effectively in extreme temperatures (-200°C to +260°C), making them ideal for use in semiconductor manufacturing, pharmaceuticals, and corrosive chemical processing. Their low friction coefficient also enhances valve actuation smoothness.

Internal Components

The internal components—such as spools, pistons, and plungers—are responsible for precise air flow control and must endure constant mechanical cycling. These parts are typically manufactured from premium brass, stainless steel, or hardened chrome-plated steel.

Brass is commonly used in standard pneumatic valves due to its excellent machinability, moderate corrosion resistance, and affordability. It is suitable for applications with low to medium wear requirements. Chrome-plated steel offers a highly durable, smooth surface that resists galling and wear, making it ideal for high-cycle applications in automotive and industrial automation systems.

Stainless steel internals are selected when corrosion resistance is paramount, especially in washdown environments, offshore platforms, or chemical processing facilities. While more expensive, they significantly extend service life and reduce downtime.

Push Button Design

The push button is the user interface of the valve and must combine durability with ergonomic functionality. Materials used include stainless steel, anodized aluminium, and reinforced plastics such as glass-filled nylon or polycarbonate.

Stainless steel buttons offer maximum durability and resistance to impact, UV radiation, and harsh cleaning agents, making them ideal for marine, outdoor, and heavy industrial use. Anodized aluminium provides a lightweight yet robust alternative, with enhanced surface hardness and aesthetic appeal due to available color finishes.

Reinforced plastics are cost-effective and allow for complex ergonomic designs, improving operator comfort and reducing fatigue during repeated use. These materials are commonly used in light-duty or indoor applications where extreme conditions are not a concern.

Corrosion Resistance

Corrosion is a leading cause of failure in pneumatic systems operating in humid, saline, or chemically aggressive environments. To combat this, manufacturers employ corrosion-resistant materials and protective surface treatments.

Valves designed for marine or offshore applications often feature full stainless steel construction or anodized aluminium housings. Internal surfaces may be coated with chrome plating or lined with PTFE to prevent pitting and galvanic corrosion. External coatings such as epoxy or powder coating add an extra layer of protection against salt spray and UV degradation.

In chemical processing plants, fluorocarbon seals and PTFE-coated components are standard to ensure compatibility with acids, alkalis, and solvents. Proper material pairing prevents galvanic corrosion between dissimilar metals and ensures long-term reliability.
