VH The VH is similar in all feature to the W3 G but specially
designed for higher output pressure range (up to 10 kg/cm2) is required.
Typically used at outlet of Hydropneumatic system where higher
pressures have to be kept to supply water to higher floors (approx 35
meters & above) and PRV cannot be installed at higher floor where
water will be drawn and thus has limitation of being installed at base
level near system only.
VL The VL is similar in all
feature to the W3 G but specially designed for the low output pressure
range (0.5 to 2 kg/cm2). The force amplifier system used enhances
sensitivity to pressure and gives uncompromised flow rate even at low
pressures. Ideal where more than 4 branches are taken in a downtake line
and lower branches will likely cross norm of 2.4 kg/cm² pressure.

Setting Outlet Pressure

Even
if a PRV is calibrated for a certain outlet pressure from factory it is
good practice to set & verify pressure at site with help of Varie
pressure testing kit* or a pressure gauge.

For
fast and efficient work the Varie specialized pressure testing kit is
recommended which has built-in arrangement for air release which helps
getting correct readings and faster work.

If the pressure testing kit is not used a simple pressure gauge with following specifications can be used:

¼' BSP end connection

50mm dial

Ideally back mounted but side mounted will also do. (PRV 40mm & 50mm needs side mounted only)

Procedure of Setting / Checking Pressure with Pressure Gauge

	Close the shut off valve (Ball valve) installed before PRV.
	If not provided then close shut off valve installed at the
	Start of down take on terrace (Or uptake line in case of hydro pneumatic system).
	Open blanking plug with 'O' ring.
	Allow residual water in line to empty out through the open port.
	Thread-in the pressure gauge in the ¼" BSP threaded port. (Ensure few turns of Teflon tape on thread of pressure gauge for sealing), Do not tighten completely. (to ensure removal of air)

	Turn on supply by opening the shut-off valve before PRV.
	Allow some water to come out thru the threads of the pressure gauge (to ensure that air is removed).
	Tighten pressure gauge completely using a spanner.
	Ensure that 'no flow' of water is there on outlet, as pressure checking / setting has always to be done in 'static' or 'no-flow' condition.
