Check Valves
The check valve is designed to use in sanitary stainless steel pipe systems. The check valve is responsible for preventing the reverse product flow. This valve is versatile because it can be installed either vertically or horizaontally. Pictured here is Alfa Laval’s “Y”-Body check valve.
High-Quality Shut Off Valves
No matter what it is containing, a shut off valve is one of the most important elements of a piece of heavy machinery. As you can probably ascertain from its name, the valve serves to cease the flow of some substance through the apparatus. Because it serves such an importance purpose, it is important to invest in a quality part.
Stainless steel is always a good bet when it comes to machinery, and this is the case with a shut off valve too. You want to look for a model that has a manufacturer warranty and guarantee that backs up the performance of the product. While the part may be relatively small, the role that it plays in the operation of the machine is huge.
Butterfly Valve
The role of a butterfly valve is to regulate the flow in which the disc takes the form of the disk. This process is similar to the process of the ball valve. The disc is positioned in the center of the pipe, and has a rod passing through, which is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel of perpendicular to the flow. The disc is always present within the flow, which means a pressure drop is then induced in the flow, no matter what the valve position is. This is the major difference from the ball valve.
Ball Valve
A ball valve is a valve with a spherical disc, which is the part of the valve that controls the flow through it. The sphere has a port through the middle, so that when the port is in line with both ends of the valve, flow will occur through it. When the valve is closed the port is blocked, not allowing the flow through. A ball valve is considered to be in the same “family” as the butterfly valve and plug valve, which is referred to as the “quarter turn valves” family.
Koss Industrial offers a wide variety of these valves including the brands TRIAC and Jamflow.
Actuators
An actuator is a mechanical device intended for controlling or moving a mechanism or system. An actuator is typically a mechanical device that takes energy, usually transported by air, electric current, or liquid, and then converts that into a type of motion.
Koss Industrial carries a wide selections of actuators; both double acting and spring return actuators.
Pressure Reducing Valve
Koss Industrial, Inc. sells the Type E Main Valve, which is a pressure reducing valve. The Type E Main Valve is a self operated, external pilot type, single seated, metal diaphragm actuated, normally closed designed valve. The internal parts of the valve consists of the seats, discs, stems & diaphragms, which are constructed of stainless steel. There are no springs in the steam space and there is no stuffing box. A major bonus of this valve is that the Type E Main Valve is easily maintained. All of the valves parts are accessible without the valve needing to be removed from the line. Pictured here is the Type E Main Valve with a D Pilot mounted on to it in order to regulate pressure.
761 Valve
The 761 Valve is the single seat valve for Alfa Laval’s line of 700 Series valves. This is an air-operated seat valve that features the positive action of either the short- or long- stroke actuator.
The 761 valve is ideal for high volume, sanitary liquid processing. The 761 possesses a heavy-duty construction and precision-molded bonnet gaskets to ensure the positive alignment under severe operating conditions.
Another great feature of the 761 valve is the sanitary and flexible design, which allows this valve to be used in a wide range of applications. For example, it can be used as a divert valve with three to five ports, a shut off, or even a cross.
Steam Ball Valves
Schubert & Salzer has the 7010 shut off valve that is also in the steam capable. These steam ball valves are not only ideal for steam, but they are ideal for water, gases, and other aggressive media. Pressures to 580 psi and temperatures to 430° F. Highest Temperatures and Pressures from any angle valve manufacturer. Materials include 316L stainless steel, bronze and brass. Actuators are available in a hardened chrome plated alloy, stainless steel and polymer. End connections include NPT, ANSI flanges, socket weld, butt weld, tri-clamp, tube ends, etc. Sizes ¼” through 3”.
Spence Valves
Koss Industrial, Inc. offers a wide selection of pressure reducing valves. One line of reducing valves that can be found through Koss Industrial, Inc. at StainlessSteelThings.com are the spence valves. The spence reducing valves, the Type E Main Valves, are generally used in fluid, gas, and vapor applications. This valve is normally closed with a single seat, and has balanced metal diaphragms with a protected spring. The Type E Main valve is virtually frictionless and has a easy in-line maintenance to help maintain a long service life.

Plug Valves
Another valve Lumaco carries, is the plug valve. Lumaco’s ITC plug valve has an ITC interchangeable Teflon encapsulated stainless steel plug that can be used in 2- or 3- way applications when unrestricted flow is a necessity. These plug valves not only meets the 3A standards, but Lumaco’s plug valves also comply with the USDA as well.
