API Certified High Performance Pneumatic Single Seat Control Valve Dn50 ANSI 300

Features
Compact structure: small volume, light weight, easy maintenance
Smooth flow channel: low flow resistance, low pressure drop, high flow
Strong anti-wear performance: The ball is subject to hard alloy spray coating, and the seat sealing face is subject to hard alloy overlaying welding.
Fire-safe and antistatic: Meeting API607 requirements, it is provided with the antistatic device.
