PremiumManufactured by Tecnidro Srlbased in ITALY
The valve avoids reservoir emptying and flooding dues to casual pipeline failure. The valve is controlled by a differential hydraulic pilot that senses flow speed closing completely main flow when senses critical speed ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
This valve controls water level in high level reservoirs to avoid overflow, without any external control system like float control etc. The valve remains completely open until the closing input is transmitted by the 3-ways piezometric altitude ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
The valve maintains downstream pressure to a constant and pre-set rate of upstream value. No pilots needed. The valve chamber is directly exposed to the downstream pressure and this varying pressure value modulates the valve to open or close according to upstream ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
The valve closes totally the pipe line when back flow occurs. The valve is complete with an hydraulic control circuit able to regulate operation’s speed during closing, preventing ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
The valve reduces high upstream pressure to a pre-set lower and constant downstream pressure level, regardless of fluctuating flow or varying upstream pressure. A hydraulic regulating pilot drives the valve. The pilot is able to detect upstream pressure values and regulates closing steps of the valve until the pre-set pressure value is ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
The valve opens fully or shuts off in response to electric signals. The valve is controlled by a solenoid that allows control liquid to flow in the upper chamber in order to close the main valve or, alternatively, drains upper chamber in order to open the main ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
The valve maintains downstream pressure over a pre-set minimum value, regardless of fluctuating flow or varying upstream pressure. Otherwise the valve may open gradually to allow surplus water flow outside the system in order to maintain system pressure to a maximum pre-set value. A hydraulic regulating pilot drives the valve. The pilot is ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
The valve isolates pumps from the system during pumps starting and stopping to protect pipe lines and pumps itself. The valve is equipped with a control solenoid valve that is switched on at pump starting and is able to fulfill pipe line gradually, reducing pressure rising peaks and allowing soft starting of the pump with closed outlet. The ...

PremiumManufactured by Tecnidro Srlbased in ITALY
The valve controls tanks and reservoirs emptying and avoids overflow. The valve operates by means of a differential hydraulic float complete with regulating levels mounted on the tank side. The float maintains the valve closed and opens only when the minimum pre-set level is reached. Once the valve is open, float allows tank ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
The valve controls downstream flow to a pre-set and constant value in order to limit water consumptions and preserve pipeline fill rate or to set a maximum demand value. The valve is controlled by a differential hydraulic pilot that senses the pressure fall generated by water flow into a calibrated ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
The valve assures maximum water level into tanks and reservoirs and avoids overflow. The valve operate by means of a modulating float, mounted on tank, able to regulate gradual opening of the valve when water level goes down from ...
-
PremiumManufactured by Tecnidro Srlbased in ITALY
This valve protects pumps and pipes from pump startup and shutoff pressure surges due to power failure. Pump off means valve normally closed. If pump starting cause pressure surge, the pilot smoothly opens the valve to limit pressure rising. Quick relief valve opens due to both pressure rises and falls, fully reducing any ...

Manufactured by Cla-Valbased in USA
The Cla-Val Model 100-02 is a hydraulically operated, diaphragm actuated, globe or angle pattern valve. It consists of four major components: body, intermediate chamber, diaphragm assembly and cover. The diaphragm assembly is the only moving ...
-
Manufactured by Cla-Valbased in USA
The Cla-Val Model 81-02/681-02 Check Valve is a hydraulically operated No-Slam Check Valve with dual speed controls. This valve opens when the pressure at the inlet exceeds the discharge pressure. A gradual rate of opening prevents sudden opening surges. When a pressure reversal occurs, the higher downstream pressure is applied to the ...
-
Manufactured by Cla-Valbased in USA
The 100-01KO Hytrol is the main valve used in Cla-Val Automatic Control Valves for high differential applications requiring remote control, pressure regulation, solenoid operation, rate of flow control or liquid level control. The Anti-Cavitation Trim components can be retrofitted to existing valves if the application indicates an appropriate ...
-
Manufactured by Cla-Valbased in USA
The Cla-Val Model 81-18 Check Valve is a hydraulically operated No-Slam Check Valve. This valve opens when the pressure at the inlet exceeds the discharge pressure. A gradual rate of opening prevents sudden opening surges. When a pressure reversal occurs the higher downstream pressure is applied to the cover chamber through the control tube ...
-
Manufactured by Cla-Valbased in USA
Cla-Val 39 Series Anti-Slam Air Release and Vacuum Breaker Valves protect piping and equipment against water hammer, surge conditions and vacuum formation during filling or draining operations. Often installed adjacent to pumps or at high points in a pipeline, they perform the following four functions in potable water, raw water and ...
-
Manufactured by Cla-Valbased in USA
The Model 100-01 is the basic valve used in nearly all Cla-Val automatic control valves. It is the valve of choice for system applications requiring remote control, pressure regulation, solenoid operation, rate of flow control, liquid level control or check valve ...
-
Manufactured by Comercial Metalúrgica Albacetense S.L.based in SPAIN
New DCP Cometal hydraulic valve was born as a response to the hydraulic needs that occur in a facility where there is a pressurized fluid and high efficiency in the hydraulic control of any condition of pressure and flow, with total confidence, security and precision is required. Initially it is released to the market for 2 "(50 mm) in ...
