Safety Valves - Series 140

Overview

ASME SECTION VIII FOR AIR-GAS

Our Series 140 is designed for heavy-duty applications where a compact valve is required. It offers excellent seating characteristics with fast-action reseating, minimizing medium loss and improving energy efficiency. Built to endure rugged industrial conditions, these valves provide high-capacity flow rates for air and inert gases.

Usages

Ideal for compressors, receivers, gas lines, air and gas receivers, piping systems, tanks, steam cleaners, sterilizers, and autoclaves.

Features

• Accurate set pressures for precise operation
• Polished stainless steel ball-seat for optimal sealing
• Pressures up to 450 PSI for high-performance needs
• Fast-acting fixed blowdown to minimize loss
• High flow capacity for efficient pressure relief

Options

• BSPT or BSPP inlet connection for system compatibility
• Female connection for flexible installation
• Full stainless steel construction for enhanced durability
• Pull ring or lift lever for easy operation
• O2 cleaning for oxygen applications
• Viton seating for chemical resistance
