Al Kl O Wafer style Knife Gate Valve, Type A Datasheet Technical changes kept in reserve The A model knife gate is an uni-directional wafer valve designed for general industrial service applications. The design of the body and seat assures non-clogging shut off on suspended solids in industries such as: > Pulp and Paper > Mining > Bulk handling > Wastewater treatment plants > Power plants > etc. > Food and Beverage > Chemical plants Sizes DN 50 - DN 1200 larger diameters on request Standard flange connection > DIN PN 10 and ANSI B16.5 (class 150) > other flange connections are available on...

Al Kl O Wafer style Knife Gate Valve, Type A Datasheet Technical changes kept in reserve Design Features > BODY: Wafer style cast monoblock with raised face, with reinforced ribs in larger diameters for extra body strength. Internal cast-in gate wedges and guides allows for tighter shut-off. Full port design for greater flow capacity and minimal pressure drop. Internal design avoids any build up of solids that would prevent valve from closing. > GATE: Stainless steel gate as standard. Gate is polished on both sides to avoid jamming and seat damage. Bottom of the gate edge is machined to a...

Al Kl O Wafer style Knife Gate Valve, Type A Datasheet Technical changes kept in reserve Other options > Bonnet (Fig.1): Assures tight sealing to atmosphere for using with hazardous gas or fluids. Reduces packing maintenance. > V-port: 60 degree and pentagonal port design. Selection depends on type of fluid control desired. > Flush ports (Fig.2): Allow for cleaning of solids trapped within the body cavities that can obstruct the flow or prevent the valve from closing. Purging can be made with air, steam, liquids, etc. depending on the process. > Other materials of construction: Special...

Al Kl O Wafer style Knife Gate Valve, Type A Datasheet Technical changes kept in reserve Valve extensions The extension on a valve allows the operator to open or close the valve from a distance. Different types of extensions can be used depending on the application and the distance from the gate to the actuator. > Floor stand Mainly used to facilitate the operator in opening and closing the valve at normal operating level. Required dimensions: H1: distance from centre line of the pipe to the base of the floor. d1: (wall bracket) distance from the wall to the face of the connecting flange....

Al Kl O Wafer style Knife Gate Valve, Type A Datasheet Technical changes kept in reserve > Tube • Stem and yoke assembly remains in its original position. • Handwheel is replaced by a tube, which rotates when operating the valve. • Stem rises and lowers within the tube. • Ideal for surface box operation, valve can be operated with a T-bar and a square nut. Required dimensions: H1:distance from centre line of the pipe to the base of the floor. d1: (wall bracket) distance from the wall to the face of the connecting flange. Notes: 1. Handwheel or square nut operated only. 2. A wall bracket...
