Control valve is used in the field of industrial automation process control to transport control signal by accepting adjust the control unit to change medium flow, pressure, temperature, liquid level etc technology parametric control element. It's composed by executing agency and valve. According to trip characteristics, Control valve can be divided into DKZ and angular travel; According to executing agency, function and character, it can be divided into linear characteristic, equal percentage features and parabolic characteristic etc. Control valve is suitable for air, water, steam, any kind corrosive medium, mud, oils etc medium. Control valve is also divided into pneumatic control valve, electric control valve, hydraulic control valve and self-actuated regulator.
There are many kinds valve body for Control valve, frequently-used valve body are single-seat, pass-through two-seater, dihedral, diaphragm, small flow, tee, eccentricity rotating, butterfly, telescope-feed, ball type etc.
The structural performances of Control valve are:
1. S series maximum working pressure: 14MPa; M and L series maximum working pressure: 10MPa; Working temperature range: -20 degree~90 degree.
2. Many structural style can be alternative (Routine for the card set of connection), the OD from φ 2mm to φ 8mm.
3. Panel mounting is convenient to install, have horizontal type, angle type two kinds.
4. Materials adopt 304/321/316 high quality stainless steel etc; Packing seal material is polytetrafluoroethylene and fluororubber.
5. Diameter of adjust hole: S series is φ 1.2mm; M series is φ 2mm; L series is φ 3mm.
6. Needle taper: S series is 1 degree; M series is 3 degree; L series is 5 degree.
7. Control valve can adjust flow to zero, but can't be used for globe valve, can add globe valve to open and cut.
The features of Control valve are:
1. To ensure the safety of storage tank, need to set breather valve on the tank deck.
2. Don't need to add energy, it can work in electroless and air-free occasion; It is convenient, saving of energy and cost reduction.
3. Breather valve is only to protect its safety and avoided conventional nitrogen sealing device in the opening and closing frequent defects easily damaged.
