Product Overviews:

Hebei tongli production of stainless steel stem all welded ball valve medium pressure trunnion ball valve temperature control range is in commonly: - 30-150 °C. Stainless steel stem all welded ball valve medium pressure trunnion ball valve  are widely used in hot water, oil, heating, chemical, heat pipe network, and so on.

Stainless steel stem all welded ball valve medium pressure trunnion ball valve diameter and temperature corresponding to the table:

Standard Features:

*All wafer and lug type BFV are designed to allow for 2" of insulation

*Wafer body features 2 or 4 flange alignment holes for easy installation

  Lugged body with drilled and tapped holes may be used for dead-end service(Please specify when ordering)

*ISO 5211 top flange for easy actuation

*One-piece shaft design, blow-out proof,ensures positive disc positioning and accurate flow control.

*3 shaft bushing/seals provide shaft support for proper alignment and backup for the primary shaft seal formed by the disc/seat interface

*disc edge is machined and polished 360º to assure low friction,which results in low operating torque plus increased seat life

*Precision taper pins,vibration-proof,ensure positive shaft-disc connection

*The phenolic-backed,non-collapsible,resilient seat is perfectly secured and fully lined in the body,which isolates the body componenets from the media and provides the primary shaft seal.Seat is field replaceable.

*Absolutely tight shut-off in either flow direction

*Can be installed in any desired direction

custom:
Our conventional butterfly valves are made of cast iron and are ISO certified. But because of their own material reasons, not in a special environment for long-term work.. But because of their own material reasons, not in a special environment for long-term work, so our factory on the traditional product innovation, our products are now all the replacement. Now, any part of our products can be customized and replaced for specific environments and jobs.

Actuator Mounting

Note:

        Prior to mounting,the part-turn actuator must be checked for any damage

        Damaged parts must be replaced by original spare parts

 Mounting ia most easily done with the valve shaft pointing vertically upward.But mounting is also  possible in any other position ;the actuator may be mounted in any position.

 The QT-series electric actuators are supplied with a female drive output.the ISO5211 bolt patterns  are provided for actuator mounting.The actuator drive bush is removable for ease of machining.

 It is mandatory for the actuator to be firmly secured to be a sturdy mounting bracket or directly  mounted to be valves' ISO mounting pad.High tensile bolts or studs with spring locking washers  must be used.

 The valve outpot shaft must be in lined with the actuator output drive to avoid side-loading the  shaft .To avoid backlash,flexibility in the mounting bracket or mounting should not be allowed. 

our test for our product

   The installation environment, we simulate the real measurement on the pipeline under different pressure and medium environment, testing our valve working condition

Packing:

We use high quality plywood wooden case packing which avoid fumigation.It have good cushioning performance,

high strength,and corrosion resistance.The use of foam film cover the valve better to protect the valve body and

fixing wooden cases is the final step.
