Shakazshura All meters supplied with flanged end connections utilize slip-on flanges as standard. Cavitation, a common problem in pumps and control valves. Sign in to check out Check out as guest. Add to watch list. As fluid flows into mefer chamber, the blocking rotor is forced to rotate and the movement of the fluid is translated from linear motion to rotational motion. Fluid enters a reciprocating piston meter, also known as an oscillating piston meter, through an inlet port.

H10 and H25 from the hydramotor series are available in both push an pull power stroke, with a choice of either spring-return or lock-in-last position upon loss of power. With minimum service requirements and a prolonged service life. The need for gears has been eleminated in favor of a modular design using fewer moving internal components and industry proven heat-resistant seals — immersed in oil for continuous lubrication.
The Hydramotor H11 serie is the result of over 50 years of experience in designing, testing, manufactoring and servicing electrohydaulically powered actuators. H11 serie of hydramotor is available in both push an pull power stroke, with a choice of either spring-return or lock-in-last position upon loss of power. Considerable field experience has proven the H11 series to be extreme reliable. The shaft retracts on application of power; lock-in-last position on power failure, spring-return when relief valve is energized.
Normally-closed relief valve wired independently of motor circuit. The Hydramotor H24 serie is the result of over 50 years of experience in designing, testing, manufactoring and servicing electrohydaulically powered actuators.
H24 serie of hydramotor is available in both push an pull power stroke, with a choice of either spring-return or lock-in-last position upon loss of power. Considerable field experience has proven the H24 series to be extreme reliable. An optional and patent pending Posi-Prove system dynamically tests valve seal tightness and conducts a self-check automatically upon system startup. The patent pending double block valve design of the Hydramotor H incorporates the following unique features: Two shut-off valves within a single body reduces gas train length and cost.
Two independent operating shafts accomplish valve closure. Unique flange design makes installation and maintenance easy. Inlet screen prevents debris from obstructing valve closure and improves seal life. Manual tester or optional Posi-Prove system verifies seat closure integrity. Visual position indication of both valves is standard. Standard valve construction uses silicone-free lubricants. Maximum operating pressure differential up to 25 PSI.
The new Hydramotor actuator incorporates two separate means of releasing the actuator shaft when de-energized. The actuator enclosure meets Watertight, Dusttight, Driptight and General Purpose requirements and eliminates the cost associated with stocking separate actuators. Besides the Hydramotor H Valve we can deliver al other Hydramotor series as well. The H11 series is suitable for water, oil, gas and steam.
It is an electrohydraulic linear actuator and has an extended iron cast. The Hydramotor H12 Shutoff Valve is a 2-way, normally closed valve with a bronze body. The H12 series is suitable for water, oil, gas and steam. The Hydramotor H15 Shutoff Valve is a 2-way, normally closed valve with a steel alloy body. The H15 series is suitable for water, oil, gas and steam. The Hydramotor H62 Shutoff Valve is a 2-way, normally closed valve with a carbon steel body.
The H62 series is suitable for water, oil, gas and steam. The actuators are widely used in nuclear power plant systems.
They provide critical safety functions such as valve and damper operation. The AH90 and NH90 Hydramotor Series of Linear Actuators features a completely self-contained, hydraulic power system that has been integrally coupled to a hydraulic cylinder. The positive, firm positioning actuators are ideal for providing efficient and precise linear control of valves, dampers, louvers, and a wide variety of other equipment requiring an operating thrust of up to 1, lbs.
Other types of the General Controls Hydramotor ah series are: General Controls ah90, ah, ah91, ah, ah92, ah, ah93, ah, ah94, ah, ah95, ah, ah96, ah, ah97, ah, ah98, ah and ah99, ah Other types of the General Controls Hydramotor nh series are: General Controls nh90, nh, nh91, nh, nh92, nh, nh93, nh, nh94, nh, nh95, nh, nh96, nh, nh97, nh, nh98, nh and nh99, nh Transmissions Up to 3 miles 5 km for current output and ft 30 m for voltage output are no problem for the Barton A Preamplifier.
The output is field selectable — for compatibility with various readout devices. Hazardous location explosion-proof condulet connects to the turbine meter coil boss. Barton Model EU Preamplifier Cenelec Approved The ITT Barton Turbine Meter Preamplifier Model EU converts low-level turbine meter pickup coil signals to square wave signals suitable for transmission up to 3 miles 5 km for current output signals and up to ft m for voltage output signals.
The output is field selectable for either current or voltage — for compatibility with a wide variety of readout devices. The Barton EU mounts directly to the turbine meter coil boss. ITT Barton Model The Barton Model Differential Pressure Unit DPU is a mechanical device which accurately measures differential pressure relative to a gas or liquid flowing through a process system, or to the level of a liquid contained in a process vessel.
For process flow measurements, the DPU of the Barton model is connected across a primary device a venturi, an orifice plate or a flow tube located in the process system.
For liquid level measurements, the DPU may be connected in a variety of ways to measure the difference in pressure caused by variations in the level of the liquid in the process vessel.
The dual bellows assembly consists of two opposing internally connected liq-Venting uid-filled bellows, a center plate, Connection range springs, overrange valves, Torque Tube and a torque tube assembly. Shaft The pressure housings are connected by Pipe or tubing to the primary device located in the sys-Mounting tem piping. Variations in differen-Bracket tial pressure within the pressure housings cause the bellows to expand or contract in a linear direction towards the side having the lowest pressure.
The linear movement of the bellows is converted into angular rotation when transmitted to the torque tube shaft by the drive arm and this mechanical motion actuates the mechanism of the process monitoring instrument. The process monitoring instrument that is connected to the torque tube assembly may be an indicator, a switch, a transmitter, a recorder, or other process control device.
BARTON model differential pressure indicators are available for a variety of safe working pressures and differential pressure ranges. The Barton model are widely used for the measurement of differential pressure, flow rate and liquid level applications. It is driven by a precision-jeweled rotary movement that multiplies rotation of the torque tube through a gear and pinion to the pointer. The movement employs a thermally stable Ni-Span-C hair spring.
Linearity adjustments are readily accessible after removal of the scale plate. Special scales can be furnished for indicating liquid level in horizontal or non-uniform tanks. Scales are available in black with white lettering standard and in white with black lettering optional.
For process flow measurements, the DPU is connected across a primary device e. See Table , page 4. The range springs of this BUA are contained within the bellows and do not come in contact with the measured liquid.
The range springs of these BUAs are grouped around the outside of the bellows. The dual bellows assembly consists of two opposing internally connected liquid-filled bellows, a center-block, range springs, overrange valves, and a torque tube assembly.
The pressure housings are connected by pipe or tubing to the primary device located in the system piping. Variations in differential pressure within the pressure housings cause the bellows to expand or contract in a linear direction towards the side having the lowest pressure. The model is widely used in jet engine and missile testing programs, aircraft ground support equipment, water treatment processes and airconditioning systems. Commonly used and recommended for liquid level indication of materials such as LOX, helium, hydrogen, nitrogen, CO2, and argon.
