Gate valve is the most common type of valve in any process plant. It is a linear motion valve used to start or stop fluid flow. In service, these valves are either in fully open or fully closed position. Gate valves are used in almost all fluid services such as air, fuel gas, feedwater, steam, lube oil, hydrocarbon, and all most any services. Gate valve provides good shutoff.
A knife gate valve works by lifting a plate with a planar or “knife” edge from the path of flow that can literally cut through various impediments during closing thereby creating complete closure against a soft sealing surface. This soft sealing surface generally dictates use in rather low-pressure systems and is not designed to handle high pressure. Both gate and knife gate valves are primarily designed for isolation or on/off service rather than a throttled or partial-flow application.
Stop-check valve is a check valve with override control to stop flow regardless of flow direction or pressure. In addition to closing in response to backflow or insufficient forward pressure (normal check-valve behavior), it can also be deliberately shut by an external mechanism, thereby preventing any flow regardless of forward pressure.
Globe valve is used to stop, start, and regulate the fluid flow. Globe Valves are used in the systems where flow control is required and leak tightness is also necessary. Globe valve provides better shut off as compared to gate valve and it is costlier than gate valve.
Metal Seated Ball Valve is manufactured for high temperature up to 540℃ (may be higher based on the material of body and trim) or abrasion resistance. Metal Seated Ball Valves are Zero leakage (bubble tight seal). Metal Seated Ball Valve is also called metal to metal ball valve, as the seat and ball are made from metal.
The tilting disc valve accomplishes full flow opening by having the disc pivot or “tilt” in the flow of the media, which causes the TD series to have an incredibly low opening stroke range. This reduces the opening and closing times critical to controlling flow reversal and reducing water hammer. Available in both top and bottom mount configurations.
The design of pressure seal valves is specifically for high-pressure applications typically in excess of 1,000 psi and are therefore normally only available in pressure classes of 600# and above. These valves are unique because as their internal pressure increases, the body-bonnet joint seal improves. This is in complete contrast to other types of valves where an increase in internal pressure creates leaks. In this article, we will discuss how the pressure seal valve works, the pressure seal bonnet vs. bolted bonnet design, and pressure seal gaskets.
A Butterfly valve is a quarter-turn rotary motion valve, that is used to stop, regulate, and start the flow. Butterfly valve has a short circular body. Butterfly Valve is suitable for large valve applications due to Compact, lightweight design that requires considerably less space, as compared to other valves.
Plug valve is Quarter-turn rotary motion Valve that uses a tapered or cylindrical plug to stop or start the flow. The disk is in plug shape, which has a passage to pass the flow. Plug valve used as on-off stop valves and capable of providing bubble tight shutoff. Plug valve can be used in vacuum to high-pressure & temperature applications.

Our most frequently requested flange, the Weld Neck Flange features a neck extension and weld bevel. Provides a natural form connection ideal for larger, high-pressure applications.
A simple alternative to the Weld Neck flange, a Slip On Flange is designed to accept the pipe into the center/bore, allowing welding around the outer diameter of the pipe.
Designed to cap off a line, a Blind Flange has no bore or inner diameter. They are often altered to include NPT threads or custom bore holes to function as hubless Slip On flanges.
Sometimes referred to as Counter Bore flanges, the Socket Weld types have a socket to insert pipe when space limitations make Weld Neck flanges difficult to use.
Threaded or Companion Flanges contain a female NPT threaded center for connection to male threaded piping. These flanges are commonly implemented in reducing connections.
Lap Joint Flanges are intended to saddle over a stub end fitting. They feature an extended hub and a machined radius at the base of the flat face.
