Eliminating product emissions is one of the most serious challenges for process industry and consequently can be most costly to control.
As part of its Health & Safety initiative campaign Habonim has introduced additional Security to the valve stem design for critical applications.

L-O-X energy isolation valves are designed to shut off the air supply and exhaust downstream air. This product can be locked and padlocked in closed position, and serves as an energy isolation device as defined by DIN EN 1037 "Safety – Machinery".
EEZ-ON valves are designed for a gradual buildup of downstream air pressure. This permits cylinders or other work elements to move slowly into their normal working positions before full line pressure is applied.
Consolidated L-O-X/EEZ-ON valves combine both pressure buildup and energy isolation functions. They can also be used as energy isolation devices as defined by DIN EN 1037 "Safety – Machinery".

The unique ELEVENT valve design with deep-drawn full stainless steel metal housing, modular assembly as well as interchangeable components offers an optimised protection for low pressure applications.
The set pressures range from 2 mbar to 200 mbar. The ELEVENT provides advanced seal technology and extreme stability despite low weight. The uncomplicated assembly of the valve and the very easy disassembly by means of clamp body connections are additional path-finding features of the ELEVENT.
The optimised “air cushion“ sealing principle provides a smooth valve stroke and re-seating during operation and prevents from valve flutter and wear.
Installation and storage costs are reduced to a minimum and costs for maintenance and inspection have never been lower!

SAFETY VALVES
This series of switch valves have been developed due to the safety level that Gas installations with Low, Average and High pressure require. Called SHUT %u2013 OFF, they get operational immediately when a electrical power %u2013 off is detected, making impossible to conect them automatically %u2013 requiring the oversight of a Technician. A review of the Gas System must be done and latter reassemble the valve.
They are made with an iron body with coiled or binded connection of 1" to 3", and pressures from 0 to 5 kg/cm2.

Hydratron has many years of experience in designing and manufacturing Relief Valve Test Benches ( PSV Test Benches ) which are suitable for testing 1/2" up to 24" valves having screwed or flanged connections at pressure of upto 14,500 PSI ( 1,000 Bar ) using water or gas as the test medium.
Valves under test can either be hydraulically clamped or fastened to the test bed and safety shields are fitted to protect the operator.
Panel mounted test gauges monitor the pressure in the valve undergoing test and full data logging facilities can be provided which allow charts to be produced and test data to be stored for future reference.
Portable units can be supplied with fork lift pockets or mounted within containers complete with lifting tackle, work bench and vice.
Alternatively static units are available for installation in maintenance workshops or production lines.

Online safety valve test system, PreVenTest
Pressure safety valves are installed on process equipment to release excess pressure due to upset process operations, external fires and other hazards. Or simply said; the safety valve serves to protect life and property. Failure of pressure safety valves to function properly when needed could result in the over pressure of vessels, exchangers, boilers, or other equipment they where installed to protect. It is essential to maintain your pressure safety valves and relief valves in good condition.
Periodically testing is one of the most important elements to proof that the safety valves will provide the so important protection. Obviously, the most desirable type of test is one that subjects the pressure relief valve to the full operating conditions that it is to endure in practice.
The Ventil PreVenTest system is a robust, but ingenious build system for testing all types and sizes of spring operated safety valves on-line, in process and under the normal operating conditions. The portable system enables you to proof the correct working and performance or identify safety valves in need of repair without plant shut-down.
Capabilities
- Unlimited range.
- Robust portable system.
- Universal and equipped for all brands.
Optional features
- ATEX Intrinsically safe version.
- 50 kN set for testing with no or a limited process pressure.

Wellhead Control Panel
Standard:
API RP14A Subsurface Safety Valve Equipment, Ninth Edition, December 1994
ASME Boiler and Pressure Vesser Code
National Electrical Code (NEC)
API RP 14C
Application:
Designed ESD system as per latest technical specifications and the actual working conditions. Apply to the effective control of SSV (surface safety valve), SCSSV (surface-controlled subsurface safety valve) and wing valves, etc.
Features:
Well opening via hand/electric/air-operated pump, meanwhile, it features pressure self-maintaining and automatic compensation, any pressure drop due to ambient temp drop or leakage, the accumulator will automatically compensate the pressure.
High & low pressure sensors are installed on the wellhead oil transmission line, in case of higher or lower pipeline pressure than the set value, the high and low pressure sensors will cut off the control circuit quickly, thus, the wellhead is turned off.
In case of a fire on the wellhead, the fusible plug will be melt when the ambient temperature is reaching the melting condition, so that to shut down the wells.
Automatic pressure relief. Surplus high pressure will be released to maintain the wellhead normal operation whenever temperature changes or mis-operation happened.
Suit high & low temperature environment (-30~60℃).
Stainless steel and rational structure design effectively isolates the natural gas and power, safer and explosion-proof.
Control types: single well with single valve, single well with multi-valve, and multi-well with multi-valve.
Both manual control and remote control for emergency shut down.
