Product Description

Application
·  Complying with GB, ANSI and other standards

·  Control valves for applications that require tight cut-off and low adjustment requirements in various industries

·  Nominal diameter: DN40 ~ DN400, NPS 1-1/2" ~ 16"
·  Nominal pressure: PN16 ~ PN63, ASME CL150, CL300
·  Temperature range: -60° C ~ +540° C

Features
·  Various valve body materials for selection, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials

·  With upper and lower shafts used to fix the ball, the ball will not move from side to side due to the influence of pipe pressure, so the valve seat will not be damaged and provide sealing performance

·  The valve seat is designed to be supported by spring to press the ball, the valve seat features small torque and stable sealing performance that lead to a long service life

·  Fire-proof, anti-static and anti-blowout stem structure for selection

·  Suitable for various working conditions with soft and hard sealing for selection and hardenable sealing surface

Supported Actuator
