31000 Series Eccentric Rotary Control Valve with PFA Liner

Features

Excellent Performance
The eccentric rotary plug design provides excellent throttling control accuracy, low dynamic forces and tight shut off. The straight through flow pattern results in high flow capacities.

Corrosion Resistance
PFA lining with guaranteed minimum wall thickness provides resistance to most corrosive fluids.

Reduced Fugitive Emissions
The rotary design inherently reduces wear on the packing as compared to a typical linear valve. Additionally, the standard design includes PTFE/Graphite packing, chevron rings, backed up by a double O-ring follower to provide further reliability in corrosive applications.

Ease of Maintenance
The compact dimensions and low weight design allows for easy installation and removal without compromising piping forces.

Reliability
The dovetail grooves provide mechanical anchoring between metal body and PFA lining to ensure high performance under vacuum and at high temperature. The powerful, field proven rolling diaphragm actuator provides positive fail-safe action. The actuator linkage is totally enclosed that comes with a combination hand wheel and adjustable limit stop with locking mechanism. All actuators are available with a complete line of options and accessories.
