Product Introduction

A Pressure-Operated Valve for Demanding Service

The ASCO 290 Angle-Body Piston Valve (also known as the ASCO Series 8290) is a pressure-operated, direct-acting piston valve engineered specifically for demanding fluid control applications that require high reliability, high flow rates, and a long service life. Its unique angle-body configuration provides a straight-through flow path, achieving exceptional flow capacity (high Cv values) with minimal pressure drop, ensuring energy efficiency and optimal system performance.
Constructed from rugged Bronze or 316L Stainless Steel bodies, this series offers broad media compatibility, making it the ideal choice for handling challenging substances such as steam, hot water, corrosive fluids, light oils, and even light slurries.

Key Advantages and Technical Breakthroughs

1. Reliability and Durability of the Piston Mechanism
Exceptional Cycle Life: The piston operator ensures fast, responsive opening and closing action. Unlike conventional diaphragm valves, the piston design is built to withstand millions of cycles under high frequency and pressure, drastically reducing downtime.
High Temperature Stability: With no diaphragm to fail, the piston design delivers far more stable operation in systems with fluid temperatures up to 185℃/ 365℉. This makes it a critical component for CIP/SIP (Cleaning/Sanitization In Place) environments in the food and beverage industry.
