Features

• The eccentrically-mounted disk design provides an approximate linear flow characteristic and can be used for throttling or on/off control applications through 90 degrees of disk rotation.
• Trim and bolting materials are available for applications involving sour service. These constructions comply with the recommendations of NACE MR0175-2002.
• The optional ENVIRO-SEAL™ packing system is designed with improved sealing, guiding, and loading force transmission. The ENVIRO-SEAL packing system can control emissions to below the Environmental Protection Agency limit of 100 ppm for valv
• Standard valve construction includes conductive packing to provide electrical bonding for hazardous area applications.
