Bidirectional Vs Unidirectional Knife Gate Valve

The replaceable steel reinforced perimeter seat is mechanically retained between both halves of the two piece bolted body for unsurpassed performance in the most demanding applications.

Bidirectional vs unidirectional knife gate valve.

The bray series 752 bidirectional knife gate valve features a robust steel reinforced perimeter seat which provides bidirectional zero leakage shutoff. The uni directional knife gate valve can also be used in harsh aggressive environments high temperatures. So you re probably wondering why don t i skip the confusion and just install all bidirectional knife gates. Bi directional knife gate valves will seat on either side.

Mvs knife gate valve can be operated through hand wheel rising stem and non rising stem chain wheel lever bevel gear electric actuator pneumatic cylinder and hydraulic actuator. Designed for easy quick conversion between manual and pneumatic actuation. Bi directional knife gate valves will seat on either side of the gate and operate with back pressures providing adequate water tightness and has a tendency of avoiding any build up of solids that could prevent the valve from closing. Knife gate valve seat options include metal seat and resilient seat which can be offered as unidirectional and bidirectional.

You can expect to pay about 30 more for a bi directional knife gate valve. The series 740 bidirectional knife gate valve provides repeatable bidirectional shutoff in a rugged single piece cast body featuring a replaceable steel reinforced elastomer seat for enhanced sealing the bray series 740 gate valve is easily automated for on off applications.
