Model 2300A is built of corrosion resistant material throughout. Groth’s self-closing special TEFLON “cushioned air” pallet with center stabilizing stem and peripheral guiding provides uniform seating and alignment. Superior performing TEFLON seating diaphragms are standard to minimize sticking caused by resinous vapours and atmospheric moisture. The guides support a spun weather-hood which covers and protects the entire valve structure. As added protection against the entry of foreign matter, a mesh screen encircles the valve under the weather-hood. Buna-N, VITON, and other seating diaphragms can be provided when required.

Emergency Pressure Relief Valve 2100 is built of corrosion resistant materials throughout. It is designed with independently adjustable springs which load the cover and keep the valve tightly sealed until set pressure is reached. Model 2100 features VITON seating to insure a tight seal.

Emergency-Relief-Valve-Pilot-Operated-2500a  Assentech- Geodesic Dome Installation

Assentech were subcontracted to assemble and install a 25m geodesic dome for Shaft G on the Lee Tunnel project. My experience with Assentech from pre-contract through to assembly has been very positive. Unlike other subcontractors I have experienced on this project, Assentech had a very positive attitude to producing the level of documentation required for a project of this scale. Leading to a high quality pre construction packaged approved in a timely manner. The communication regarding the manufacturing process was first class allowing us to easily plan our works and prepare the site. Dome assembly was carried out very efficiently and completed to programme. The task was correctly resourced and well supervised. The work force had a positive attitude and carried out the task safely. In summary from my perspective it has been a very easy subcontract to manage with a high quality finished product.
