Gate valves

Gate valves are primarily used to enable or prevent a fluid medium to flow (i.e. ON / OFF control). A fully open gate valve results in no obstruction to the flow path, thus allowing for very low friction losses.

FACTS GATE VALVES

• Threaded and flanged gate valve designs

• Depending on gate valve design, suitable for water and liquids with abrasive particles, saturated steam, oil, air and gas

• Non-rising stem

• Flanged gate valve features slider vulcanized with rubber to guarantee tight shut-off

Globe valves

Globe valves are primarily found in fluid regulation applications. Their (semi-) spherical form is comprised of two body halves, separated by an internal baffle. Shutting the globe valve is achieved by means of a disk, which screws into the seat of the battle by means of a handwheel or actuation. As opposed to ball valves, the flow of the medium is not direct and in one direction, instead the fluid enters and rises inside of the body of the valve prior to exiting on the other side.

FACTS GLOBE VALVES

• Wide range of body materials, including cast iron, ductile cast iron, SG-iron steel, and stainless steel

• Flanged and threaded globe valve designs

• Depending on product type, suitable for a wide range of applications and media, maintenance-free

• Cold and hot water, steam, nitrogen oxides, gas, air, oil, chemicals and various acids

Check valves

Check valves are primarily used to fully close the passage of a circulating (gaseous or fluid) medium in one direction and to simultaneously allow free passage in the other direction. As two-port valves, they feature two openings in the body, one by which the fluid can enter, and one by which it can leave.

FACTS CHECK VALVES

• Threaded, flanged or closable check valves designs

• Depending on the check valve design: suitable for water, non-aggressive liquids and gases, steam, condensate

• Depending on the check valve: universal, horizontal or vertical mounting

Bellow seal valves

Bellow valves feature a metal bellows, usually cylindrical in shape, to protect against stem leakage. Functioning like a vertical diaphragm, it seals with the valve stem and the valve body itself. This type of valve is used to minimize air pollution, losses in production, problems in the process and energy losses.

FACTS BELLOW SEAL VALVES

• Used in combination with heat transfer media, vacuum, highly hazardous or costly fluids
