Product Desciption
VF45 Mixed valve series High closing force flange type two way regulating valve
Composition of SDCHENXUAN Temperature Control Valve
Controller:Accept the temperature signal and output 0...10V control signal through P/PI/PID operation. Common models of Siemens controllers include RWD60 \ RWD 62 \ RWD68 \ RLU36 \ MZ730 - b, etc.
Actuator:
Accept the adjustment signal sent by the controller, accurately adjust the valve opening, stable operation, optional power-off reset, 3P or analog adjustment, 230DCV or 24DCV power supply. The common models of Siemens actuators are SUA21\SQS65\SSC85\ SAX61\SKD62\SKB62\SKC62, etc.
Valve body:
The executor that regulates the flow of medium is matched with the executor to form an electric regulating valve. Siemens valves are divided into: copper valves, cast iron valves, ductile iron valves, cast steel valves; According to the connection mode, it can be divided into: threaded connection and flange connection valves; According to the medium used, it can be divided into water valve and steam valve. Diameter DN10 ... DN150.(chenxuan DN15-DN300)
Sensors:
The temperature of the medium is measured in various types. According to the installation position, it can be divided into immersion temperature sensor, binding temperature sensor, air duct temperature sensor, indoor temperature sensor, outdoor temperature sensor and other types.
Common Knowledge of SDCHENXUAN Temperature Control Valve Selection
1. The valve material, flow capacity and actuator shutoff force shall be comprehensively considered according to the type of heat medium ( steam / hot water ), temperature, pressure parameters and operating conditions ( heat exchanger type, opening / closing system ).2, when used for steam flow control, generally refers to 98 % dryness of saturated steam. If it is superheated steam, due to the change of steam adiabatic index k and the corresponding change of fluid viscosity coefficient, it is generally necessary to recalculate and check.
3. The medium flow rate has a square root relationship with the differential pressure before and after the valve. Excessive pressure difference not only produces noise, but also has cavitation effect on valve body, affecting service life. The light ones are not tightly sealed, and the heavy ones may explode, causing casualties and other major accidents.
4. Excellent temperature regulation curve is the guarantee to realize temperature control effect. Except for the special requirements of the fast thermal system, the valve shall be of equal percentage or parabolic type as far as possible.
Equal percentage: q / qmax = r ( l / lmax - 1 )
Parabolic: Q/Qmax=1/[1+ ( r - 1 under radical ) l / lmax ] 2
5. Electric temperature control valve shall not be used as stop valve for a long time. Please shut down when stopping the machine.
6. The two-way valve must not be used as a three-way valve by removing the blind plate on the valve base.
7. When using equipment produced by a third party to match Siemens products, attention should be paid to meeting safety requirements.
8. The temperature control valve cannot use a direct water supply system and must be circulated. If it is an instant heat exchanger, a heat storage tank must be added.
9. When working in domestic hot water, please distinguish between 24 - hour hot water supply and regular hot water supply.
Product features :
- Precision casting (resin sand) nodular cast iron GGG-50
- The valve body adopts the pressure balance type, which guarantees the high clearance ability under the low pressure, and the switching free ability under the high pressure difference
- Maximum allowable differential pressure is 1000kpa
- The stem seal uses special sealing process
- The full metal joint seat increases the value of the life of the valve
- The product meets GB/T17213-2015 flange connection standard
- the body uses iron coated sand casting process compared with the traditional technology, there is no swelling phenomenon, body wall thickness, no pores, trachoma material of high density, more exquisite appearance The valve body and stainless steel valve port in the casting process once molding, the valve port will not have deformation phenomenon, long time high temperature use will not exist outside the valve leakage phenomenon, to ensure that the valve port factory pressure test 0 leakage. The sealing ring is made of PTFE+ carbon fiber material, which has better wear resistance The paint paint line and drying equipment make the paint adhesion stronger, the anti-corrosion effect is better, the valve body gloss has been significantly improved.
Suitable for Continuous Control in Regional Heating System and HVAC System.
It can be installed with Siemens SAX, SKD, SKB, SKC series executor.
