High pressure parallel slide gate valve.

Venturi parallel slide valve bonnet bolted as shown on valves class 600 pressure sealed bonnet on class 1000 and above. Parallel slide gate valves blackhall manufacture world renowned taylorshaw parallel slide gate valves which are used in high pressure and high temperature applications. Parallel slide gate valve provides a smooth flow path between seats. System pressure is used to provide isolation.

Full bore parallel slide valve bolted bonnet on class 150 600 excluding class 600 modified 9 cr valves. By pass valves have a parallel slide gate design with a pressure seal bonnet a forged body butt weld ends can be motor operated and are in accordance with mss sp 45. By pass valves parallel slide gate valves can be fitted with by pass valves when specified by the customer. Two discs and just one wedge design gate valve.

Unique parallel slide forged cage unit design comprises all operating parts of the slide discs. This design of gate valve is commonly used for clean fluids and steam applications. Pressure seal valves are engineered and manufactured in strict conformance to asme ansi astm api and other applicable standards. Parallel slide gate valves pressure seal configuration both designs accordingly asme b16 34 and en 12516 dimensions from 2 inch to 36 inch pressure classes 600 900 1500 2500 end to end as per b 16 10 or as per customer request class 4500 and intermediate high pressure classes with very short pattern.

Used in high pressure and high temperature applications the unique design of the taylor parallel slide isolating gate valve allows it to maintain fluid tightness without the aid of any wedging action thereby eliminating mechanical stresses between the discs when opening or closing the valve. Diagram shows 150 class valve. The closing is only made over one of the seats. Available in variety of high quality material combinations and end connections a prolonged life and minimal maintenance is ensured for customers.

Class 600 modified 9 cr valves. The dsi pressure seal product line offers flex wedge and parallel slide gate valves straight and y pattern globe valves swing lift and tiltdisk check valves. Velan pressure seal parallel slide gate valves are ideal for clean service and steam. The eyelet follower conduit design provides long reliable service life and allows for high seat velocities without detriment to service life.
