How It Works
A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.
Gate Valves
Gate Valves
Specifications
| Size Range | Various |
| Connections | Threaded (NPT), Socket Weld, Flanged |
| Body Material | Cast Iron, Cast Steel, Brass-Bronze, Ductile Iron |

How It Works
A gate valve is the most common type of valve used in any process plant. It is a linear motion valve used to start or stop fluid flow. When the gate valve is fully open, the disk of a gate valve is completely removed from the flow. Therefore, virtually no resistance to flow. Due to this very little pressure drops when fluid passes through a gate valve. In service, these valves are either in a fully open or fully closed position.
Globe Valves
Globe Valves
Specifications
| Size Range | ½” – 24” |
| Connections | Threaded (NPT), Socket Weld, Flanged |
| Body Material | Cast Iron, Cast Steel, Brass-Bronze, Ductile Iron |

How It Works
A globe valve is a linear motion valve used to stop, start, and regulate the fluid flow. The globe valve disk can be removed entirely from the flow path, or it can completely close the flow path. During the opening and closing of the valve, the disc moves perpendicularly to the seat. This movement creates the annular space between the disk and seat ring that gradually closes as the valve closed. This characteristic provides the globe valve good throttling ability required for regulating the flow.
Safety Relief Valves
Safety Relief Valves
Specifications
| Size Range | ½” – 6” |
| Connections | Threaded (NPT), Socket Weld |
| Body Material | Stainless steel, Bronze, and Cast Iron |

How It Works
The SVB Safety Valves are used for over-pressure protection on unfired pressure vessels in saturated steam systems. Valves are 100% factory tested and made in the USA. In the event steam pressure increases to the set point, the safety valve will “pop open” discharging steam faster than it can be produced; allowing system pressure to return to safe levels at which point the valve will close.
Steam Mixing Valves
Steam Mixing Valves
Specifications
| Size Range | ½”, ¾”, 1”, 1½” |
| Connections | Threaded |
| Body Material | Brass |
Contact Us for more information on this product and to see other sizes that fit unique applications.
How It Works
The steam mixing value mixes steam and cold water and controls thermostatically the outgoing hot water. Hot water will be produced only, when the hot water outlet will be opened.
Bellow Seal Valves
Bellow Seal Valves
Specifications
| Size Range | ½” – 26” |
| Body Material | Stainless Steel, Carbon Steel |
Contact Us for more information on this product and to see other sizes that fit unique applications.
How It Works
A bellow seal valve has a compact structure and is one kind of control valve to balance the pressure. It is an accordion-like metal tube fastened to the valve stem and to the bonnet, forming a leak-proof seal with negligible friction.
Butterfly Valves
Butterfly Valves
Specifications
| Size Range | 1½” – 24” |
| Connections | Flanged, ANSI Flanged |
| Body Material | Stainless Steel, Carbon Steel |

How It Works
A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The “butterfly” is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway.
Triple Offset Butterfly Valves
Triple Offset Butterfly Valves
Specifications
| Size Range | 3” – 48” |
| Connections | Flanged, ANSI Flanged |
| Body Material | Stainless Steel, Carbon Steel |
Contact Us for more information on this product and to see other sizes that fit unique applications.
How It Works
A Triple offset valve has a conical angle between the valve and valve seat allowing the disc to seal against the seat with no friction. Triple offset valves are generally used in applications similar to gate valves where a metal seat is required, and a tight shutoff and/or quarter turn actuation is desired.
