Description

Butterfly valves series series PA300 is a butterfly valves with a symmetrical disk, and the elastomer seat.

By default, the connection type is wafer, but may also manufacture with flanges or with threaded lugs. When installed butterfly valves do not require additional seals, elastomer seat covers body from both sides and the contraction of the stopper between the flanges provides tightness of the connection.

Seats are available in removable and in-situ option (by means of curing) and have a bi-directional seal without leaks.

The design feature of butterfly valves series PA300 in that the working medium is not in contact with the valve body. Therefore, the working characteristics of the valve depend on the materials of the seat and disk.

Butterfly valves series PA300 are used in a various industries: heating, water supply, ventilation, conditioning, gas supply, etc.
