The externally piloted angle–seat valve is operated with a single or double–acting piston actuator. The actuator is
available in two different materials, depending on the ambient temperature. High flow rates are attained with the
virtually straight flow path. The reliable self–adjusting packing gland provides high sealing integrity. These
maintenance-free and robust valves can be retrofitted with a comprehensive range of accessories for position
indication, stroke limitation or manual override.
Angle seat vavle
Flow to open valves are anti–waterhammer design (the line pressure dampens the closing). Flow to close valves
for gases and steam can generally use smaller actuators, at a lower cost but may require higher air pilot
pressure to open and may have a lower flow capacity Cv.
The products will be sent out together by Fedex, DHL, TNT, or SF Express and so on. Of cause, if you
have a special requirements, we will do as you told.
The company for the products are brand new original products, no second-hand and refurbished products, or
