Product Description
The wedge gate valve (soft-sealing) model 504 is designed for fully shutting off flow in water systems where high tightness, durability, and the ability to operate in various installation positions are required.
Thanks to the use of ductile iron and a flexible rubber-coated wedge, the valve ensures reliable tightness even in the presence of small solid particles in the medium. The design allows installation in both horizontal and vertical pipelines, and operation can be manual or powered by pneumatic, hydraulic, or electric actuators. Its robust construction and proven materials make model 504 ideal for water supply systems, industrial installations, and technological systems requiring high reliability.
Design features of the model:
-
Body and wedge made of ductile iron with high mechanical strength
-
Rubber-coated wedge – ensures complete sealing and resistance to particle presence in the flow
-
Stainless steel stem – high durability and corrosion resistance
-
Bidirectional installation possible (horizontal/vertical, in any flow direction)
-
Available with various types of actuators: manual and automatic
Working media:
-
Clean and raw water
-
Water containing small solid impurities
-
Non-aggressive aqueous solutions
