Product Description

YG13H pressure adjustable control valve---Internal thread high sensitivity steam pressure reducing valve

This valve is mainly used for steam pipe, apply to the steam pipeline which inlet pressure and flow rate with big changing.


YG13H Internal thread high sensitivity steam pressure reducing valve (pressure adjustable control valve) is a kind of piloted piston valve. Consists of main valve and pilot valve two parts. The main valve is mainly composed of valve seat, the main valve plate, piston and spring. Pilot valve is mainly composed of the seat, disc, diaphragm, spring and adjusting spring.

Set spring outlet pressure By adjusting the spring, diaphragm transmit the sensing outlet pressure changes, the pilot valve opening and closing which drive piston to adjust the throttling flow area, realize the control function of pressure controller. The products are mainly used for steam pipe, is pressure reducing and sustaining valve.

Compare to ordinary pressure reducing valve, this model valve made the following improvement:
Increased the piston area, changed the structure of throttling, changed the seal form, improve the pilot valve structure and regulation of the spring form, so as to improve the performance of the valve from the following aspects.
1. Improved the transforming performance to outlet pressure changing, improved the sensitivity, and greatly reduced the pressure deviation due to changes in upstream pressure and flow changing.
2. Improve the streamline distribution, reduced noise.
3. Improve the sealing surface structure, extend the service life.

Reducing valve; Pressure reducing and sustaining valve
The pressure reducing valve is a pressure control valve which with throttle method make the outlet (downstream) pressure lower than the inlet (upstream) pressure, and keep the downstream pressure constant by reducing it to desired pressure, the desired pressure can be set according to the needs. The downstream pressure keeps constant and won't change by the upstream pressure changing or upstream flow rate changing.

Analyses them from the fluid mechanics point, the pressure reducing valve is a throttling element which local resistance is changeable. The reducing valve by changing the throttling area, change the kinetic energy of the flow velocity and fluid, produced different pressure loss, so as to achieve the goal of reducing pressure. And then through the adjustment of the control and regulation system, make the valve downstream pressure fluctuations and spring force keep equilibrium, the valve downstream pressure keep constant (no change or change within the error tolerances).

Tianjin U-ideal Instrument Co. Have Many different kinds of pressure reducing valve, such as: The piloted piston type pressure reducing valve, diaphragm pressure reducing valve, bellows type pressure reducing valve, proportional pressure reducing valve, self-reliance type pressure reducing valve, direct acting piston type pressure reducing valve, back pressure regulator, etc. They apply respectively to different working medium.
