Self-Operated Temperature Regulators

Principle of operation
Self-operated pressure regulators are control devices whose measuring units draw their energy from the process mediun which creates sufficient force to move the final control element(plug with plug stem).
The regulators consist of a valve and an actuator which either opens or closes the valve when the pressure increases.The regulators are proportional regulators controlled by the process medium.Each deviation from the adjusted set point is assigned a certain valve plug position.
Pressure reducing valves
Pressure reducing valve or pressure reduing stations withdraw as much energy from a pressure vessel with a higher pressure level as needed to maintain a nearly constant pressure level in downstrem equipment, although consumption fluctuates.
The pressure p2 to be controlled (controlled variable x) produces the force fm=p2 x a, which is proportional to the controlled variable, on the diaphragm area a.This force corresponds to the actual value and is compared at the plug stem with the spring force fs=set point


Media:water
Port size:1/2''~12''

RTZ-H Gas Pressure Regulator also named RTZ-H gas regulator, RTZ-H pressure regulator. It is a device which is used to control pressure during the process of gas delivery. RTZ-H gas regulator has a direct-acting spring loaded mechanism, which works by changing the gas flow in the valve and keep the outlet gas within the prescribed scope. This type gas regulator performs well in reducing or increasing pressure. It is suitable for civil gas regulation applications.
RTZ-H gas pressure regulator has good flow capacity and high pressure control accuracy. It is extensively used in the gas supply applications, such as indoors gas pressure control system, industrial gas pipeline system and high-rise buildings additional indenter regulation. The specifications of RTZ-H gas regulator can be customized according to your requirement.

For Hydraulic Pressure Compensated Flow Regulator Valve equivalent to HydraForce FR10-30F, AAK received the re-peat order from customer in the USA

Last May, one of our old customers in USA placed an order for a hydraulic Pressure Compensated Flow Regulator Valve equivalent to HydraForce FR10-30F.

The FR10-30F is a screw-in, cartridge style, pressure compensated, non-adjustable hydraulic flow regulator valve. It CAN be used as a priority type flow regulator, delivering the pump flow to priority port 3 first, then bypassing excess to port 2; or a restrictive type, 2-way flow regulator when the bypass port 2 is blocked.

In Ningbo China, there are several hydraulic cartridge valve manufacturers who have this model. After testing the samples from manufacturers in Ningbo, the customer placed their order with AAK due to AAK s stable quality.

Till now, it has been over 1 year since we shipped the first order. We are very happy to hear that customer will place their re-peat order for 500 pcs this week.

The advantages of AAK Hydraulic Pressure Compensated Flow Regulator Valve E-FR10-30F are:
1. The quality of this valve is benchmarking HydraForce, but price is much cheaper.
2. The service life is 2 times that of domestic hydraulic cartridge valve manufacturers in China

Technical parameters of AAK E-FR10-30F Hydraulic Pressure Compensated Flow Regulator Valve:
Max. Operating Pressure: 240 bar (3500 psi)
Flow Ratings:
Priority Flow Rating: 0.4 to 22.7 lpm (0.1 to 6.0 gpm)
Inlet Flow Rating: 37.8 lpm (10.0 gpm) Maximum
Cavity: VC10-3

AAK E-FR10-30F Hydraulic Pressure Compensated Flow Regulator Valve, benchmarking HydraForce FR10-30F, its service life is 2 times that of its domestic peers. You are welcome to give it a try.
