Product Description

Intelligent Control Automatic Damper Hydraulic Control Valve 
MODEL NO. BFDZ70(1/2/3/4/5)X



The KARFAR model BFDZ70X is multifunctional, remixing check valve, globe valve and pressure surge eliminator. It is mounted at the outlet side of the pump to stop backflow, start pump under-loading, eliminate pressure surge etc. It works to protect pump station, equipment and pipeline in the system. The opening range of the disc can be adjusted in a digital displayer of the disc opening step controller. At the same time, direct currency 4-20MA is output to the computer controlling centre. 
This model is popularly used in industry of metal refining, petrochemical, oil, city construction, environment protection, water conservancy project. 

Feature: 
1, Micro resistance: 
Open & close is actuated by the direction change valve. The big disc opens and closes quickly with small resistance.
2. Small size:
 Because of butterfly disc type, the valve volume is only one third ~ one fifth of other silimar function valves. It needs much smaller space for installment.
3, Light in weight:
Weight is one third ~ one fifth of similar valves, thus save a lot of cost.
4, Long service life:
Tilting sealing line leads to better self-compensation of sealing face abrasion.
5, Automatic operation:
The valve and the pump works interlocked by medium in the pipe. No need of manual operation. Valve will open when pump starts. Valve will close when pump stops.
6, Energy saving:
t is automatically operated by the medium pressure. No need for extra power.
7, Excellent sealing:
Double sets of sealing, soft sealing and hard sealing in order to guarantee longtime drip tight.
8, Smooth operation:
Due to offset structure of this disc, it has small friction torque so opening and closing is very smooth.
9, Easy maintenance:
The control system is mounted outside the valve so it is easy to adjust or fix it.
