Manual Check Valves & Actuators

Manual Check Valves & Actuators

Manual check valves with actuators uniquely combine standard check valve functions with manual override or control capabilities. They permit fluid flow in only one predetermined direction under normal operating conditions, automatically closing to prevent reverse flow. The addition of manual actuators, such as hand levers or wheels, allows operators to manually override valve positions, facilitating testing, maintenance, and operational adjustments when required.

The primary advantage of these valves lies in their dual functionality: automatic flow protection combined with manual control. The automatic check feature protects critical equipment and processes from damage due to reverse flow, surges, or unexpected pressure reversals. Manual actuation capability provides operational flexibility, enabling quick isolation, bypassing, or system testing without removing the valve from service, significantly enhancing maintenance efficiency and system reliability.

Manual check valves and actuators find extensive application across various industries, including chemical processing, oil and gas production, water and wastewater treatment, power generation, pharmaceutical manufacturing, and HVAC systems. Their robust, versatile design is ideal for situations demanding routine maintenance, frequent testing, or periodic isolation to ensure system integrity.

Typical applications include isolation and verification of pump discharge lines, protection of compressors and instrumentation from reverse flow, bypass operations in critical pipeline sections, and facilitating regular system tests or inspections. These valves significantly improve operator safety, reduce downtime, and enhance overall operational efficiency and control in complex industrial fluid-handling systems.
