UPVC pneumatic ball valve

Corrosion-resistant UPVC ball valve for control of aggressive media — acids, alkalis, saline solutions — in chemical processing, water/wastewater and pharmaceutical service. Lightweight, durable body with a pneumatic actuator for fast 90° quarter-turn operation. NAMUR-compatible interface for direct automation; multiple end connections for high-purity and corrosive duty.

Product Introduction

Plastic pneumatic ball valves serve acid/alkali and chemical-handling systems — particularly where instrument air is available and explosion protection is required. Their light weight and corrosion resistance make them suitable for pure-water, potable and process-water, drainage and sewage, and brine and seawater systems.

Features

Corrosion resistant — UPVC/CPVC construction withstands strong acids and alkalis with no rust or scaling, for broad media compatibility.
Easy maintenance — union-end design allows quick disassembly and service.
Sanitary — non-toxic material meets applicable hygiene/food-contact standards.
Lightweight — approx. 1/5 the weight of steel and 1/6 that of copper equivalents.
Durable — high strength and toughness with good abrasion resistance.
Low resistance — smooth bore minimizes flow loss and media adhesion.
