Product Description
Weiling Piston Pressure Reducing Valve:

Purpose
The main purpose of this device is setting at user’s will the installation’s pressure at own valve's outlet. It benefits that
all devices and equipment installed after the valve (downstream) work with a constant pressure, avoiding ram effects
and optimizing the using life of all of them.

APPLICATIONS
The most common applications are: plumbing in general, heating, water and fluid networks in general that aren’t
corrosive. All fluids should be free of lime and solid particles. This pressure regulating valve is a special device to
achieve the desired outlet pressure setting. Outlet pressure can be set using the adjusting nut (6). It’s widely used in
high buildings, municipal water supply networks, mines, underground garages, etc. to guarantee all the water
consuming at different position in the supply system can obtain the desired water pressure.

MAXIMUM WORKING TEMPERATURE
Due to materials’ quality used for manufacturing this valve, working temperature’s range is from 0 ºC to maximum
80ºC. However, to extend using life of the valve it’s suggested that the valve usual working temperature’s range
doesn’t exceeds from 50 ºC.

WORKING PRESSURE RANGE
Inlet maximum nominal pressure is 16 bar.
Outlet pressure can be set from 2 bar to 8 bar. It’s recommended not to exceed outlet maximum pressure of 8 bar
so as not damage internal parts of the valve.
This valve is supplied with pre-setted outlet pressure 3.5 bar. When inlet pressure is 10 bar or above, outlet pressure is 3.5 bar with a tolerance of ± 0.5 bar. When inlet pressure is less than 10 bar, outlet pressure is in accordance with inlet pressure because it’s a reducing valve not a multiplier.

ADVANTAGE
1. Precise Pre-setted Outlet Pressure;
2. Flexibility: Outlet Setted Pressure can be Adjustable as needed, much more flexible and can be used under different occasion.
3. Piston Type design, more accurate and longer lifetime.


INSTALLATION:

The PRV(Pressure Reducing Valve) must be installed, set and tested by a qualified plumber. During assembling, suitable tools must be used so as not to damage the valve or its connections. For a correct operation, flow direction marked in the body of the pressure reducing valve must be respected. It’s suggested to clear out to all the installation before assembling this valve.

Ensure that there is no leakage between pressure reducing valve and its connections to the pipe. Check that connections to the pipe are free of tensions, such as traction, torsion or bending.

Choose the optimum size of the pressure reducing valve, according to the size of the installation pipe, its flow rate and desired working pressure.

Ensure that the fluid to set is compatible with materials, features and working temperature of this valve.

To set outlet pressure, first remove bonnet cover and use a special tool to adjust the adjusting nut to get the requested outlet pressure. Screwing on (clockwise) adjusting nut, outlet pressure increases. Unscrewing (anti-clockwise) the adjusting nut, outlet pressure decreases.

It’s advisable to realize regular maintenance to make sure that internal filter is normally working and it’s not clogged.
