High Performance Butterfly Valve Vs Butterfly Valve
The construction of this butterfly valve ensures that the following are fulfilled: - Quarter-turn operation. A handwheel is used to turn the valve open via a gear system. All of our high-performance valves are manufactured to the highest industry technical standards that include the American Petroleum Institute (API), the American National Standards Institute (ANSI) and other international standards of quality. DIN ISO PN16/PN25 to 2500 kPa (25bar). Hydrocarbon Processing Gas Piping. The actuators may use hydraulic, pneumatic or electric power to turn the shaft and operate the butterfly valve. NSF/ANSI 61 – portable water. The triple offset design is used where bubble tight shut-off, zero leakage is required in common applications such as steam, chemical, refining, and offshore oil and gas.
FEIDA stainless high performance butterfly valve is extremely durable with innovative double offset design and could meet one million operations. This type of valve is suitable for many industries, including shipbuilding, chemical processing, petrochemicals, oil and gas, power generation, and pharmaceuticals. Maximize flow and minimize resistance providing high Cv. This butterfly valve design is ideal for applications that have space constraints or a smaller valve is required. The most common seat material is polytetrafluoroethylene (PTFE) or reinforced PTFE (RTFE) because of the wider range of compatibility and temperature range. Maximum strength stem for high-torque applications. Materials of Construction|. Metal Seat (Cryogenic) -320°F to +250°F (-196°C to +121°C).

H-Series for highest performance. Pressure Testing of Steel Valves. Product Description. High-performance butterfly valves for hydrocarbon service generally do not have a preferred flow direction and are bi-directional. A double offset butterfly valve is a high performance butterfly valve. Electric actuators are powered by an electric motor and are used in applications where there is a need for remote operation. By using a double-offset design a PTFE seat and a fire-safe (metallic) seat may be used to achieve zero-leakage and a fire-safe design. FEIDA high performance butterfly valve is an innovative double offset design product with advanced world leading technology.

Hydraulic actuators are also available in single-acting (spring return) or double acting (hydraulic to open, hydraulic to close). Vacuum: up to 1 mbar absolut. Shipbuilding - Power plants - Civil engineeringOpen the catalog to page 1. NACE MR0175/ ISO 15156. This means the seat will not take a "set" while sitting in storage or on the shelf prior to installation. LUG TYPE PROCESS VALVE T 214-C.
Double Flanged High Performance Butterfly Valve Sawamura
Construction of Huamei Double-Flanged Butterfly Valve. AISI 410, AISI316, 17-4Ph, Monel® K500, UNS32760, Titanium. Essentially, manual butterfly valves are operated by levers or handwheels attached to a gearbox that drives the shaft. 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. API 598 ISO 5208, API 6D, EN12266-1. The Triple-Offset design uses a torque seated design allowing the valve to open and close with contact occurring on the seating faces only when the valve is closed. Lug-Type Butterfly Valves have lugs which are cast integral to the valve body.
WCB, LF2/LCC, - F1, F5, F9, F11, F22, F44, F51, F53, F55, - AISI 316, 304/L, CF8/M, CF3/M, 316/L, 321, 347, - Monel, Inconel, Hastelloy. Design: To meet the customer requirements in flow control systems, Value Valve is constantly developing our products to be a superior product choice in sever applications. Power / Co-Generation Plants Steel and Iron Works Commercial. With this design of valve when the disc in the valve pulls through a non-metallic, typically elastomeric liner which also acts as the seat or seal for the valve. Metal to metal seat leakage is rated at Class IV per ASME/FCI 70-2. DNV GL, Sour Service. WAFER TYPE PROCESS VALVE T 211-C. QUALITY FEATURES PTFE-VALVE. Nominal diameter: DN 80 - DN 600. Huamei, however, does an alternate method involving shaping the upper stem bore to fit a squared or hex-shaped stem. ANSI Class 600 2″-24″ (50-600mm). Double off-set configuration with conical angled disc design. 2" – 24" / DN 65 – DN 600 – Wafer, Lug, or Double Flange. 2½ " – 14" Pipe Flanged and Flanged Fittings. Fire safe: API 607 Certified.
Double Flanged Butterfly Valve Vs Lug Type
Working Pressure: Class 150 (285 psig); Class 300 (740 psig). 316 stainless steel (SS) bearings for long service life. Cycle life up to 2, 000, 000 cycles. A Double-flanged butterfly valve is easier to mount and center, and is also mechanically stronger in construction than lug or wafer design, making it suitable for heavy-duty, large flow-handling scenarios. Safety Integrity Level||Risk Reduction Factor||Probability of Failure on Demand|. All Rights Reserved. SS304 / SS316 / SS316L / Inconel / Titanium. JIS B2210: 10K, 16K, 20K. BUTTERFLY VALVE Q 011. Butterfly valves can be used in throttling / flow control, or on-off control.
Its compact size makes it an attractive option when compared to other types. When closed the valve stops the flow of media (either gas or liquid). HP 600# 20in~24in W-L, Flanged. Gland flange preventing uneven load distribution against packing. The wafer type butterfly valve, also known as non-lugged is sandwiched between two pipeline flanges.
The most common type of manual actuator is the lever. ANSI Class 600 to 1440 psi (10000 kPa). PED: 2014/68/EU, Safety Integrity Level. The Kv-value [m³ per hour] is the flow of water at a temperature of 5°C to 30°C (41°F to 86°F) at ∆p of 1 bar - The Kv-values specified are based on tests carried out by the Delfter Hydraulics Laboratories,.. the catalog to page 4. Fire-safe designs are offered that provide the shutoff of a polymer seat valve before a fire, and the metal seal backup provides shutoff during and after a fire. Pressure ratings: - ANSI Class 150 to 285 psi (2000 kPa). Their maximum corrosion protection ensures an extremely long service life even in the harshest operating conditions. Double-flanged butterfly valve in double-eccentric construction.
The lever is attached to the shaft of the butterfly valve and used to turn it. This promotes easy installation, alignment, and safe usage as these valves can be used in many different industries. This along with the two eccentric shaft offsets, allows the disc to seal against the seat with no friction. Valve Inspection and Testing. It is capable of providing accurate, stable, throttle flow control.
