BALEM 138-020 consists of Basic Valve (BALEM 130) , Solenoid On-Off Pilot Valve and the limit switch. The valve can control solenoid pilot valve according to an electrical signal so valve opens and closes rapidly. The valve has dual Normal Open type solenoid valves and dual Normal Close type solenoid. When Power failure or leakage occurs the valve senses the flow and closes promptly for preventing the damage in pump filed or automatic control system. - Size: 50A (3") -300A (12") - Operating Pressure: 0. 5-15 kgf / cm2 - Temperature: 0-80 Celsius Degree - End Connection - Flanged: 10kgf / cm2-ANSI 150 Standard - Screwed: KSPT (BSP) -NPT Standard - Media: Water

BALEM 133-040 consists of Basic Valve (BALEM 130) , Pressure Relief Pilot Valve (Model 573) and Pressure Reducing Pilot Valve (Model 562) . The valve is installed at Bypass line for protecing pumps and pipe-line systems from dangerous surges caused by rapid chagnes of flow velocity within a pipeline. The valve has anticipated the down pressure caused by the abrupt stopping of the pump and opening, closing of valve, immediately opens to prevent high pressure in Pipeline and has set to minimize high pressure, relieves excessive setting pressure - Size: 50A (3") -300A (12") - Operating Pressure: 0. 5-15 kgf / cm2 - Temperature: 0-80 Celsius Degree - End Connections - Flanged: 10kgf / cm2-ANSI 150 Standard - Screwed: KSPT (BSP) -NPT Standard - Media: Water

BALEM 132-070 consists of Basic Valve (BALEM 130) , Two Pressure Reducing Pilot Valve (Model 562) and 3-Way Solenoid. It has one pilot set at a higher pressure setting for times of high water demand; a second pilot set at a lower pressure setting for low demand for getting the direct effect as saving water in a high flowing water rate. The valve needs electric power source, It needs a control system to change the desired time according to flow change of Solenoid valve. - Size: 50A (3") -300A (12") - Operating Pressure: 0. 5-15 kgf / cm2 - Temperature: 0-80 Celsius Degree - End Connections - Flanged: 10kgf / cm2-ANSI 150 Standard - Screwed: KSPT (BSP) -NPT Standard - Media: Water

BALEM 131-020 consists of Basic Valve (BALEM 130) and Two-Level Pilot Valve (BALEM 511) . It can control water level from 300mm up to 1200mm in storage tank, and mechanically on-off operation controls opening and closing when water level reaches the set heights. Double chamber structure minimizes the effect of the valve action due to whirlpool in the valve and easy to install and maintain. - Size: 50A (2") -300A (12") - Operating Pressure: 0. 5-15 kgf / cm2 - Temperature: 0-80 Celsius Degree - End Connections - Flanged: 10kgf / cm2-ANSI 150 Standard - Screwed: KSPT (BSP) -NPT Standard - Media: Water

BALEM 441 is a float hydraulic liquid level control valve for use in reservoirs. It is a solenoid operated hydraulic control valve. In case if power failure, it can be overridden mechanically by installing a pilot valve. It is suitable for and safe at high pressure flow as its opening and closing is both by solenoid and mechanical pilot valve. Its corrosion resistance and thermal resistance is excellent, and it will not contaminate the line fluid. - Size: 80A (3") -250A (10") - Operating Pressure: 0. 5-10 kgf / cm2 - Temperature: 0-80 Celsius Degree - End Connections: 10 kgf / cm2 Flanged - Media: Water - Solenoid Valve: AC 220V 60Hz, Normal Closed

BALEM 421 is a buoyancy type of water level control valve which is pilot integrated as one body for supply and controls water levels in a storage tank by utilizing the line static and differential pressure. BALEM 421 Valve has a full mechanical structure, so, it functions by itself without any external power source. It is easy to install due to inner control pipe and integrated pilot. Durability of the valve is excellent and shutting off is stable in high pressure since the valve functions by piston style opening / closing. This valve can get much flow rate of water quickly as it has pilot styled structure using the pressure difference. - Size: 25A (1") -80A (3") - Operating Pressure: 0. 5-10 kgf / cm2 - Temperature: 0-80 Celsius Degree - End Connections: KSPT & NPT - Media: Water

BALEM 521 is a combination differential pressure hydraulic / machanical type level control valve utilizing the buoyancy of the ball-float and the system pressure. Due to its simplicity it requires neither external energy sources nor additional mechanical assistance. The pilot style operation ensures tight shut off and high flow characteristics, is unaffected by relatively high pressure. Due to its plastic construction it is both lightweight and corosion resistant. - Size: 15A (1 / 2") -50A (2") - Operating Pressure: 0. 5-10 kgf / cm2 - Temperature: 0-60 Celsius Degree - End Connections: Male threaded: KSPT & BSPT - Media: Water

BALEM 411 is designed to be as hydraulic liquid level control valve in a reservoir. Its working principal is controlling folw by a ball inside the body as float arm moves up and down against weight and buoyancy of water level. It is applicable at high pressure flow as it is opened and closed by rotation of ball. Its corrosion resistance and thermal resistance is excellent. Moreover, it is easy to carry and install. - Material: Brass Body & Cap (Nickel Plated) or All Stainless Steel - Size: 15A (1 / 2") -65A (2-1 / 2") - Operating Pressure: 0. 5-10 kgf / cm2 - Temperature: 0-80 Celsius Degree - End Connections: KSPT, NPT - Media: Water
