Sierra water air valve series 6400-PP Are Hydromechanical devices designed to automatically release or admit air during pipeline filling, draining, or operation of a water pipeline or system. The safe operation and efficiency of a pipeline are dependent on the continual removal of air from the pipeline.
Combined Check Valves or Hydraulic actuators weight loaded HAWL valves are used at all critical areas where the pipelines must be reliable, immediate and controlled quickly for valve closing, e.g. in case of external power losing, cutting off electricity cables during The earthquake, disasters In a system, ruptured pipelines, etc.) While for the valve closing is used a potential energy of lifted weight.
SERIES 6400 is a single chamber aero-kinetic water air valve, which designed to prevent dynamic closure under higher air velocity.Valves has double orifice and perform three functions. The three function of the valve shall include:
SIERRA model 5400 is a swing type tilting disc check valve that is a development of the traditional type swing check valve that has been designed to allow for frequent flow reversals without causing wear in the shaft seat which is a common feature of the swing check.
The nozzle check valve is one of the faster closing check valves that reduce slam and water hammer due to its short linear stroke.The nozzle check valve design also reduces head loss during operation. Hence is one of the most economical valves.
SIERRA model 7200 is concentric rubber lined valve, double flanged or wafer type that shall be suitable for installation between flanges. Face to face according to EN 558 table 5 basic series 20 valves are drilled in accordance with EN 1092-2. The disc has a profiled sealing edge which requires minimal deformation of the liner to achieve a tight sealing.
SIERRA model 7500 is an eccentric disc seated – double eccentric – butterfly valves. Valve body and discs are designed to provide minimal flow resistance.
Sierra sewage air valve series 6600-PP Are Hydromechanical devices designed to automatically release or admit air during pipeline filling, draining, or operation of a water pipeline or system. The safe operation and efficiency of a pipeline are dependent on the continual removal of air from the pipeline.
Combined Check Valves or Hydraulic actuators weight loaded HAWL valves are used at all critical areas where the pipelines must be reliable, immediate and controlled quickly for valve closing, e.g. in case of external power losing, cutting off electricity cables during The earthquake, disasters In a system, ruptured pipelines, etc.) While for the valve closing is used a potential energy of lifted weight.
SIERRA Model 3100 – 3300 – 4300 is a ductile iron full bore double – flanged metal – seated gate valve designed to comply with ISO 5996 and BS 5163 for water, wastewater, irrigation and sewage applications
Series 7800 is double flanged eccentric resilient seated plug/ball valves which are suitable for sewage, slurry, wastewater, waterworks and raw water and applications. Valve ports shall be of round port type. The body seat shall be furnished with a welded-in overlay stainless steel seat, precisely machined inside the valve body for providing high corrosion and wear resistance, long service life and reliability.
SERIES 6600 is a single chamber sewage air valve, which designed to prevent dynamic closure under higher air velocity. Valves has double orifice and perform three functions. The three function of the valve shall include:
SERIES 5600 is double flanged rubber flapper (swing flex) check valve types suitable for sewage, wastewater, raw water and slurry applications. The valve has a full flow body type, the valve has an elastomeric flexible disc type and the disc is the only moving part that shall assures long life with minimal maintenance.
The model 1100/S Pressure Reducing Valve is a hydrauli-cally operated, diaphragm actuated, control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure, Thanks to a Sole-noid Control, the Valve will also open or close in response to a signal
The model 2400 is a pressure management valve that reduces high line pressures to lower distribution system levels, as it can switch between two pilots by means of a latching solenoid. The solenoid control feature can be activated by an electrical signal from a battery-operated controller.
The Model 2500 is a Low-Power Electronic Control Valve that brings pressure management and modulation to a new level of excellence, it is a battery-operated Pressure Reducing Valve that can operate with different control modes to optimize water network pressures.
Failure to maintain Automatic Control Valves can result in network pressure oscillation and surges, which lead to a mechanically stressed network, increased burst frequency and an increased level of Non-Revenue Water.
The mode 1300PB Safety- ACV valve is a hydraulically operated, diaphragm actuated, control valve that saves the pipe line by shutting off the water if the line was broken
The model 1400 Modulating Float Valve is a hydraulically operated, diaphragm actuated, control valve that allows flow into the tank (reservoir) in order to maintain the level at the designated maximum.
The model 2300 is a series of motorized pilots That can be used with all network control valves pressure reducing sustaing and flow limiting valves . The Motorized pilot is basically conventional hydraulic pilot that is driven by a motor remote set point adjustment .
Dual solenoid control valve is modulating valve which either opens or closes modulates receiving and electrical signal from controller to solenoid plot control
The model 1600 Altitude Valve is a hydraulically operated, diaphragm actuated, control valve that allows flow into the elevated tank in order to maintain the level at the designated maximum. The valve modulates to maintain the tank level. As the reservoir level drops the main valve is open proportionally to increase the filling
