|
| ||
| Valve Motion: | |||
| Your choices are... | |||
| Rotary Motion Valve | Rotary motion valves (rotary valves) such as ball, plug and butterfly valves that rotate through a quarter-turn (90 degrees) or more from open to close. This includes multiturn valves. | ||
| Linear Motion Valve | Linear motion valves (linear valves) such as gate, globe, diaphragm, pinch, and angle-style valves have a sliding stem design that pushes the closure element open or closed. The valve stem may rise while rotating (multi-turn) or may rise without rotating. | ||

|
|
| ||
| NEMA Enclosure: | |||
| Your choices are... | |||
| Type 4 | Constructed for indoor or outdoor use. Provides a degree of protection against contact with enclosed equipment, falling dirt, rain, sleet, snow and windblown dust, splashing water and hose-directed water. Undamaged by external formation of ice on enclosure. | ||
| Type 4X | Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, hose-directed water, and corrosion; and that will be undamaged by the external formation of ice on the enclosure. | ||
| Type 7 | Constructed for indoor use in hazardous locations classified as Class I, Division 1, Groups A, B, C or D as defined by NFPA70. | ||
| Type 9 | Enclosures constructed for indoor use in hazardous locations classified as Class II, Division 1, Groups E, F, or G as defined in NFPA (National Fire Protection Agency) 70. | ||
| Other NEMA Enclosure | |||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Actuator Action: | |||
| Your choices are... | |||
| Direct Acting | For manual actuators, clockwise rotation of the actuator causes clockwise rotation of the valve to close. For other types of actuators, increasing control input signal extends the valve stem. | ||
| Reverse Acting | For manual actuators, clockwise rotation of the actuator causes counterclockwise rotation of the valve to close. For other valve types, increasing control signal input retracts the valve stem. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
