FEIDA fire safe high performance butterfly valve is fire safe certified to API 607, 7th edition. Power / Co-Generation Plants Steel and Iron Works Commercial. When the disc is perpendicular to the bore of the valve it is in the closed position. Pneumatic actuators are powered by compressed air. DOUBLE FLANGED BUTTERFLY VALVE Z 612-A MATERIAL SPECIFICATION AND PARTS LIST Nodular cast iron Pos. VOC: ANSI/ISA-SP-93, TA-Luft, ISO 15848-1. ISO 9001: 2015, ISO 14001: P. E. D – 2015. Emissions standard to TA-LUFT, ISO 15848-1, ANSI/ISA SP-93. Double flanged high performance butterfly value inn. Metal seat: A240 Tp 316/304. Seat Material: PTFE or RTFE with Resilient Energizer. Weights for Gear & Handle.
High Performance Butterfly Valve Type Double Flange Tight Shut Off-other products 2. INFLATABLE SEAT INFLAS. Most HPBFV's have the stem pinned to the disc and the spot welded, NOT allowing removal of the Disc and Stem. Both soft and metal seats are interchangeable. Heavy duty handle and 10 position notch plates allow for positioning the valve disc to precise angle stops. High-Performance Butterfly. Others upon request. Leakage Class: ANSI FCI 70-2-2003 Table 1 CLASS V, ISO 5208 Rate A, ANSI/ISA-SP-93.
High-performance butterfly valves are designed and manufactured to provide superior sealing performance. An automatic sealing system which is independent of the flow and equipped with a special sealing profile resists even high gap velocities. Huamei, however, does an alternate method involving shaping the upper stem bore to fit a squared or hex-shaped stem. Seat available in either soft (PTFE/RTFE) NBR, EPDM, Viton or Metal (A240 Tp 316/304). Lockable position plate for wrench operated valve. NPS 2"-60"(DN50-DN1500). Carbon Steels inc. Low Temp. Double Flanged Butterfly Valves. CONTAINER VALVE BE 50/BE 80. Oil & Gas (Onshore Refinery, storage and distribution). In high-performance butterfly valves, the shutoff may be provided by an interference-fit seat design or a line-energized seat design, where the pressure in the pipeline is used to increase the interference between the seat and disk edge. Chemical / Petro-Chemical Liquified Gas / Refrigeration Heavy Industrial. WATER/ AND WASTE WATER TECHNOLOGY.
This along with the two eccentric shaft offsets, allows the disc to seal against the seat with no friction. This valve has two stems offset from the centre. Double flanged high performance butterfly valve installation. BUTTERFLY VALVE High Performance Triple Offset Metal Seated Fire Safe Cryogenic also available. Wafer and lugged designs. Stem seals are made of O-ring seals. Metal seats are also offered in high-performance butterfly valves. To EN ISO 5211 Face to face dim.
Standards and Construction. Actuator Mounting (Direct & Non-Direct Mount. Positive stem retention system above packing. Double & Triple Butterfly Valves with wafer, lugged & flanged bodies. Stocking in Sizes 2" through 36". Why SELECT SIL-3 Valves/ Actuators? This additional offset puts an angle on the seat making it a conical profile, the conical seat allows for the use of metallic sealing faces on both the disc and the seat. This type of valve is suitable for many industries, including shipbuilding, chemical processing, petrochemicals, oil and gas, power generation, and pharmaceuticals.
This type of valve can be especially helpful if your operations involve higher pressures and particulate fluids. Gland flange preventing uneven load distribution against packing. Retainer ring surface finish is 125 to 200 AARH and is compatible with both standard gasket and spiral wound gasket designs. Disc Material: Stainless Steel, Duplex Steel, Nickel Aluminum Bronze, Monel, Hastelloy, Titanium alloys. FEIDA stainless high performance butterfly valve is extremely durable with innovative double offset design and could meet one million operations.
