Top-guided globe Control Valves

The serials include follow types: pneumatic diaphragm top-guided globe control valve、 electric top-guided globe control valve、top-guided  F46-lined globe control valve.

Actuator selection: Spring-and-diaphragm, Pneumatic piston, Electric motor, Electro-hydraulic.

constructor  compact,flow path is “S” style in body,low pressure differential, low resistence coefficient and wide rangeability,flow charactristic is accurate for process, strong guide for travel.

bonnet constructor :bellows seal type、steam-jacket type 、Extension Bonnet ,etc.

1.cage-guided

a.  cage-guided constructor,stronger guided due to seal performance & longevity.
b. Quick change trims allows for easy of maintenance,no internal components are screwed and welded into valve body
or bonnet. low cost of maintenance in plants.

2. approximate uniform section of  “S” mould
low resistence coefficient,wider rangeability
3.top guide F46-lined globe control valve
F46、PFA;anti-corrosion, lining material :F46 and PFA
4. steam-jacket type
heat the medium in the pipe.
5. Bonnet type
Bellow seal type (Pressed or Welded)
6.Characteristics
Equal percentage,Linear, On-off.
7. material comply with NACE MR0175
8.Rating: 150#、300#、400#、600#、900#

according with industry standard
IEC60534 industry process control valve standards
flange standards:ANSI B16.5/B16.25

Cage double-seat control valve

The series sleeve two-seater regulator (hereinafter referred to as the sleeve regulator) is a kind of pressure balance type regulator, compact structure, small volume, simple structure, the valve body fluid channels in an s-shaped streamlined, with a small pressure drop loss, large flow, wide adjustable range.High accuracy of flow characteristic curve, good dynamic stability, low noise, low cavitation corrosion, etc.Because the valve core adopts a fluid pressure balance structure, it only needs a small operating force to achieve stable adjustment.

This series of regulating valves are easy to be made into corrugated pipe seal, heat dissipation plate, extended upper valve cover and other special structures.
