Low Torque Butterfly Valve

Low Torque Butterfly Valve BF10R Series

Having over 30 years of experience in the designing and manufacturing of Butterfly Valves, Advance Valves has widened its range by offering Low Torque BF10R Series butterfly valves to its range of Concentric, Double Eccentric & the High Performance Triple Eccentric Butterfly valves.

Advance Valves BF 10R series is a lightweight low torque butterfly valve, the compact design of which provides excellent structural stability, flow efficiency and effective sealing resulting in prolonged service life and ease of operation. A unique design feature includes a replaceable seat with tongue-and-groove design which provides complete isolation of flowing media from the body at all times. The uniqueness of this specially-designed lining is that the liner is an easy clip-on design eliminating the use of any bonding material whatsoever. This feature therefore avoids disbonding between the valve body and the liner which occurs in other valves during operations over time leading to valve-body damage and consequent valve replacement and down time.

This valve is ideal for low pressure applications upto 10 bar (150psi).

Advance Valves has optimised the requirement for actuated valves solution whereby its full range of rubber-lined concentric butterfly valves are mated to a single-phase electrical operator.

This product has a specially designed high induction motor generating a powerful starting torque. The actuator is compact and lightweight and is maintenance-free - truly a fit-nforget solution, additionally eliminating the headaches of actuator-sizing by the end-users.

Design & Performance Features Explained

  • Replaceable Seat to Body Construction:A special replaceable seat with tongue-and-groove design provides complete isolation of flowing media from the body. The sandwiched replaceable seat design eliminates the need for additional line gaskets.
  • Spherical Design of Disc & Seat:The spherical design of the replaceable seat near its contact area with the stem provides primary stem sealing and reduces the seating / unseating torque. This design not only reduces wear and tear of the contact surface of the seat but also provides tight shut-off and excellent regulating characteristics to the valve.
  • Unique Torque-Reducing Design:A specially designed double D connection in the upper stem helps to improve the efficiency of torque transfer from the valve operator to the disc. This helps in optimizing actuator selection.
  • Primary & Secondary Stem Seal Design:The stem seal design incorporates a primary seal inherently ensured by interference fit of the soft seat with the disc hub and the secondary sealing is provided by a special double o-ring design which prevents leakages even under adverse conditions.
  • Smooth Operations:The incorporation of heavy duty corrosion-free bushes avoids shaft deflection and minimizes bearing friction.
  • Integral ISO:5211 Mounting Flange:This standardized operator mounting flange is available for assembly of all operators such as hand-levers, gear-boxes, electrical and pneumatic operators further add to ease in operations.

Axial Check Valve

Axial Check Valve NZ Series

Having over 30 years of experience in the designing and manufacturing of NRVs, Advance Valves has developed the NZ Series of axial or nozzle check valves deploying advanced 3-D design software including Computational Fluid Dynamics analysis as well as thorough testing of the valve prototypes.

These valves are widely used in different industry sectors including that of oil and gas such as top site offshore platforms, subsea, refineries, pipelines, LNG and petrochemical plants.

Advance Valves NZ-Series is an axially operated non-return valve with non-slam characteristics. This valve series incorporates an efficient design with high flow rates and a low pressure-drop, thereby ensuring a high degree of reliability in operations. With these characteristics these valves can safely be used for critical process applications involving process pumps and compressors where equipment safety largely depends on efficient nonreturn valve performance.

The axial check valves are mostly installed downstream of rotating equipment to protect the expensive mechanical equipment from possible damages due to backflow. Although they are usually more expensive to other types of check valves, these valves provide safe protection of costly rotating equipment.

Many natural gas companies and other power industries are now placing their pipelines below ground and are looking for a one-piece valve they can weld in and bury. The NZ Series Check Valve answers that demand with a precision nozzle-style valve that uses axial-flow technology to eliminate turbulence and prevent erosion and vibration. This design reduces downtime and maintenance costs and boosts capacity and accuracy.

Additionally, the NZ Series Check Valve provides a critical service to the power industry due to the valves enhanced leak proofing under high pressure thereby virtually eliminating acid and chemical leakage.

Key Features of Advance Valves Axial / Nozzle Check Valves

  • Designed as per ANSI B16.34.
  • Non-slam, axially operated.
  • Self-operated, no external force required.
