Sum up:

Q947 type Electronic ball valve Suitable for two occasions cut off , regulating . Valve and connection of the executive body are adopted and connected with the way directly , the servo system is put in the electronic executive body, needn't mix the servo amplifier separately , inputting 4-20mA signal and 220VAC power can be controlled and operated! Have simple lines , the structure compactness , size are small , light , such advantages as reliable that obstruction is small , movements are steady. The executive body can dispose such such angry piston type executive bodies as type electron type electronic executive body or GTX , AL ,etc. as UNIC , PSQ , HQ , DHL ,etc. separately according to user's enquiry .

Carry out the standard

1, design and manufacture: GB12237-89 , API608 , API 6D , JPI 7S-48 , BS5351 , DIN3357.
2, the size of flange: JB/T74- 90 (JB74- 90 ) , GB9112- 9131 , HGJ44- 76 , SH3406 , ANSI B16.5 , JIS B2212- 2214 , NF E29-211 , DIN2543.
3, the length of structure: GB12221-89 , ANSI B16.10 , JIS B2002 , NF E29-305 , DIN3202.
4, examine and mainly test: JB/T 9092 , API 598.

The Q47 type regular type ball valve is a new generation's high-performance ball valve, suitable for the long-distance pipeline and general industrial pipeline, intensity , security its , able to bear abominable environment ,etc. carry on special to consider when design, it is and not the corrosivity medium to be suitable for various kinds of corrosivity. It and float ball valve compare , when working , valve fluid pressure effort that produce all transmit to the bearing at spheroid, will not make the spheroid move to the valve seat , therefore the valve seat will not bear the too big pressure , so the torque of the regular type ball valve is small, the valve seat is out of shape and small, the sealing property stabilizes, has long performance life, suitable for the high pressure , heavy-calibre occasion. Advanced spring valve flat package in advance, is it since urgent characteristic , realize the top seal to have. Every valve has two valve seats, each direction can be sealed, therefore installation has not flowed into and limited, it is two-way.
This valve has two types and three types and two kinds of valve body structure, the flange of China uses the bolted joint, while sealing and adopting strengthening the polytetrafluoroethylene (PTFE) to inlay and enter the stainless steel and enclosing, there is not a spring to guarantee the valve seat sticks to the spheroid closely in the steel rim rear, keep sealing. Upper and lower valve stems do not have PTFE bearing , reduce and grit , operates and saves effort , there is not a trimtab in the small axle bottom, guarantee a ball of connecting the place position with sealing enclosing .
All open directly: The aperture of flow of the valve keeps the same with internal diameter of the pipeline, so that the pipeline is cleaned.
