4 verview Pilot valves control trim operation High pressure in sensing chamber (): The pressure in the sensing chamber () is overcoming spring () resistance, forcing the diaphragm () up. Low pressure in sensing chamber (): The spring () is compressed by the adjustment bolt (), forcing diaphragm down. 6 6 The shaft () is moving with the diaphragm, actuating the main valve (6) by opening or closing pilot valve s internal water passages. Pilot valve set-point The pilot valve s position is determined by the forces equilibrium of hydraulic pressure and spring resistance. resistance is adjusted by the adjustment bolt (). ompressing the spring (turning the bolt in clock-wise direction) increases the regulated parameter. For example: n Pressure Reducing valves- tightening the bolt (turning in clock-wise direction) will increase the maximal downstream pressure. n Pressure Sustaining valves- tightening the bolt will increase the minimal upstream pressure. n Flow ontrol valves- tightening the bolt will increase the maximal flow rate. A specific spring has specific pressure range in which it can regulate. s are marked by different colors representing different pressure ranges. orrect spring selection is critical for the Pilot valve function. olored rings located on the adjustment bolt specify the internal spring color. The spring selection is usually done by DRT technical department according to the client s data and demands but spring replacement can be easily done by the client if conditions demand. Edition 0/0

5 verview -way pilot valve (positioning) The -way pilot valve is a selector pilot activated by the pipeline pressure which admits the control media into the control chamber to close the main valve, relieves the media from the control chamber to open the main valve, or locks the volume in the control chamber to keep the main valve throttled at a fixed regulating position. This control principle allows for full opening of the main valve when operating conditions require the valve to be fully open. -way ontrol is used for: n-ff ontrol valves. Regulating valves which need operate with low pressure differential. Dirty water as raw irrigation water and sewage water. Where usage of external control media (such as pressurized air) is required. peration principle : - Way pilot valve operation principle: (Referring to a valve that opens at low regulated pressure and closes at high regulated pressure (such as PR)). High regulated pressure: Pilot valve is connecting the valve s control chamber to the upstream. Main valve is closing. Low regulated pressure: Pilot valve is connecting the valve s control chamber to the atmosphere. Main valve is opening. Required regulated pressure: Pilot valve is preventing flow at all passages. Main valve maintains fixed position. losing pening Set-point Edition 0/0

6 verview -way pilot valve n a two-way pilot valve, the upstream side of the valve is connected by a control tube to the control chamber and to the downstream side of the valve. Two flow restrictors are assembled. ne (orifice or needle valve) assembled upstream of the control chamber and the other (a pilot valve) assembled on the downstream side and modulates in response to the pipeline pressure. The relative opening of both restrictors dictates the position of the main valve. This type of control principal provides very accurate and sensitive regulation but creates considerable pressure loss even if no regulation is needed. -way ontrol is used when: Minimal pressure differential at all operating conditions allows it. Sensitive (fast response) regulation is required. Relatively high quality water. peration principle : -way pilot valve operation principle: High regulated pressure: Pilot (b) senses a downstream pressure higher than the set-point and closes passage (b). Through passage (a) the upstream water flows directly into the upper part of the control chamber, forcing the diaphragm to close the valve. Low regulated pressure: Pilot (b) senses a downstream pressure lower than the set-point, and fully opens passage (b), larger than (a). All the water from the upstream flows through (a) and (b), directly to the downstream, allowing water from the upper part of the control chamber to partially drain. Required downstream pressure: The pilot is set to the required downstream pressure. The pilot senses when the downstream pressure reaches the required value causing passage (b) to equal passage (a) b=a. Now, water that flows through the control loop passes from (a) through (b) and into the downstream. The control media in the upper part of the control chamber is now steady, keeping the diaphragm and seal in a fixed position. a b a b a b losing pening Set-point Note: the flow through the first restricting element (a needle valve or an orifice) will determine the valve's closing rate. The flow ratios between the first restricting element and the pilot (in its fully opened position) will affect the valve's head loss when no regulation is needed. 6 Edition 0/0

14 Metal mini-pilots 68-0 Pressure-Reducing, -way metal pilot-valve The 68-0 is a -way, diaphragm actuated, spring-loaded pressure reducing pilotvalve, designed for control of hydraulic-valves. The pilot valve modulates to keep a steady, pre-set downstream pressure. As the downstream pressure falls below the set point, the pilot valve opens the water passage between its "N" and "UT" ports thus allowing the water in the main valve's chamber to vent to the downstream, and open the main valve. As the downstream pressure rises above the set point, the pilot-valve throttles the internal passage, restricting the flow out of the main valve control chamber, enabling the valve to keep its position or to close (if necessary).

16 Metal mini-pilots 68-M Pressure-reducing, -way metal pilot-valve with electronic setting (pneumatically) modulated by controller The 68-M is a -way, diaphragm actuated, spring-loaded pressure reducing pilot-valve designed for control of hydraulic valves. The pilot valve modulates so to keep a steady, pre-set downstream pressure. As the downstream pressure falls below the set point, the pilot valve opens a full passage between its n port and ut port thus allowing the control chamber pressure to be vented to the downstream side and the valve to open. As the downstream pressure rises above the set point, the pilot valve throttles the internal passage, restricting the flow out of the valve control chamber, causing it to keep position or close. Features A -way, diaphragm operated, spring loaded, spring balanced pilot, designed for pressure reducing valves Unique modulated setting pneumatic controlled pilot-valve hanges the pilot s set point according to a programmed function electronically pneumatic pressure t is normally-open, allowing water passage while downstream pressure is less than the adjustable spring setting t closes drip-tight when downstream pressure exceeds the pre set point. areful balancing of powers within the pilot - main spring, balancing spring, water pressure - ensure sensitive and accurate response to pressure fluctuations Sealing seat and inner passage are made of stainless steel, preventing erosion damage caused by continuous high velocity flow. an be activated by hydraulic or pneumatic pressure Typical applications Pressure reducing valves - PR Technical data General Pressure rating bar / 60 psi adjustment range 0. - bar / 7-0 psi Fluid temperature 80 max. / 7 F max.

32 Metal pilots XPR Pressure-Reducing, -way metal pilot-valve The XPR is a -way, diaphragm actuated, spring-loaded pressure reducing pilot-valve, designed for control of hydraulic valves. The pilot valve modulates to keep a steady, pre-set downstream pressure. As the downstream pressure falls below the set-value, the pilot valve opens a full passage between its "N" and "UT" ports thus allowing the valve to open by venting the control chamber pressure to the downstream side of the valve. As the downstream pressure rises above the set-value, the pilot valve throttles the internal passage, restricting the flow out of the main valve control chamber and causing the main valve to keep its position or to close (if necessary). Features A pressure-reducing -way pilot valve Normally-open, allows water passage when downstream pressure is lower than the adjusted spring setting Wide regulation range A single spring is used for setting range of. to 0 bar (0-00 psi).
