Start selecting your valves early in the design process! Valves play a critical role in the cost, efficiency, and safety of any piping system, and choosing the right valves can be just as critical as selecting your pipe and fitting materials. Our experienced team can help you make the right selection for your project and get your valve decisions made early to complete your piping system design.
Ball valves are quarter turn bi-directional valve designed to operate in a fully open or fully closed position. They can be used to throttle flow with the appropriate valve trim through a short curve for short periods of time. Typically, the media can flow either direction (bi-directional) through the valve. Ball valves have become the valve of choice in many industries because of their ease of operability, ease of actuation and its ability to obtain a tight seal. Because they are used in so many applications, the valves come in many different body types, seating arrangements, packings and seals, pressure classes, etc.
Gate valves are a multi-turn linear action valve that is designed to operate in a fully open or fully closed position. When open, the media will flow with a minimal turbulence and pressure drop through the valve. Typically, the media can flow either direction (bi-directional) through the valve. Small diameter gate valves (forged steel) are normally reduced port (full port is available) while large diameter gate valves (cast steel) are normally full port.
Globe Valves are a multi-turn linear action valve designed to throttle or shut off a flow. The CV value or flow capacity is less than a gate valve. The flow direction and pressure is designed to be under the disc, so they are a unidirectional valve. The design of the valve allows for an even flow of media with minimal turbulence through the throttling curve.
Check valves are designed to prevent reverse flow and are a unidirectional valve. There are many different styles of check valves. The most common check valve is a swing check. Check valves are available in a wide variety of body types, body and trim materials and designed for general and specific applications. They come in a broad range of pressure classes and end connections.
Butterfly valves are a quarter turn bi-directional valve designed to work in a fully open or fully closed position. Butterfly valves have evolved over recent years and have started to become the valve of choice in many industries because of their ease of operability, ease of actuation, ability to obtain a tight seal, and because they are more economical, lighter weight and have a shorter profile than a ball valve. Butterfly valves were first used in municipal and commercial water applications but can be found in all industries today. The valves come in many different seating arrangements and closing techniques.
Knife gate valves are a short profile valve that is designed for dirty slurry services and is used extensively in the pulp and paper industry as well as mining.
Plug valves are an on/off quarter turn valve and are available in two basic designs: lubricated – high maintenance and non-lubricated sleeved or lined. Lubricated plug valves are widely used in dirty applications that would normally score the seats and balls of a ball valve. Sleeved or lined plug valves are found in corrosive applications.
Thermoplastic valves are highly corrosion-resistant, non-toxic, will not contaminate fluids, and will not scale or rust. They are frequently used in systems that were previously designed in metal.
Lined valves are made with a plastic material, usually a fluorocarbon, covering all wetted surfaces, so the media never comes in contact with metal parts. Liner materials can include PFA, PVDF, PTFE, PFA-AS (antistatic), and UHMWPE.
Sampling valves allow the user to take a small part of the fluid in the system for testing or sampling purposes. These valves are typically used for quality control or regulatory assessment purposes.
Solenoid valves use an electric current to generate a controlled magnetic field. The magnetic field controls the opening or closing of the valve to regulate fluid flow.
