This assembly regulates oil temperature while maintaining correct minimum internal system pressure, ensuring proper lubrication, efficient oil separation, and stable compressor operation.
Designed for 415V three-phase Variable Speed (VSD) screw compressors, this genuine replacement thermostat valve helps maintain energy-efficient performance and protects the air-end from premature wear.

What Does the Combined Thermostat Valve (Including MPV) Do?
In an oil-injected rotary screw compressor, this combined unit performs two essential functions:
1️⃣ Oil Temperature Regulation
The thermostat valve controls oil flow through the cooler to maintain correct operating temperature. This ensures:
Proper oil viscosity
Effective air-end lubrication
Prevention of condensation
Stable compressor efficiency
2️⃣ Minimum Pressure Control (MPV)
The integrated Minimum Pressure Valve maintains internal pressure during start-up and operation, ensuring:
Correct oil circulation
Efficient oil separation
Stable discharge pressure
Protection of internal components
By combining both functions in one assembly, this unit ensures reliable compressor performance and controlled operating conditions.
Signs Your 11kW Thermostat Valve May Need Replacement
A faulty thermostat valve or MPV can cause:
High or unstable oil temperature
Slow pressure build-up on start-up
Oil carryover into the air system
Reduced separation efficiency
Increased energy consumption
Premature wear of compressor components
Replacing the combined thermostat valve restores correct operating temperature and pressure stability within your 15HP screw compressor.

Hi Sam, Thank you for taking time to review our company. I'm so glad we were able to help! Kind regards Team CAS
I can't recommend CAS UK enough. We had a Clarke for a couple of years that we abused running it 12 hours a day. We found CAS UK when it needed a repair, and we were very impressed with how quickly they responded and came out to repair and service the machine.
Our business started to expand and we needed a large compressor with a proper airlines feeding our machines and work stations. The guys from CAS supplied the new compressor and worked flat out getting the machine and pipe working in. They're a brilliant group of lads with a great work ethic and really easy to communicate with.
We'll 100% continue to use and recommend them.

Took in what I believed to be a beyond repair compressor. Received back, an as new machine, all physical damage repaired and connector fittings renewed to latest standard. Compressor delivered to my premises in what was a great service by Compressed Air Systems UK. Thanks for a great experience
Me and my company have been using compressed air systems for around 10 years! Very professional always great advisor for the best machine for what we need, friendly office staff and most of all the knowledge from them is second to none. Would recommend to anyone that needs advise or want to buy the right machine for them. Plus the backup you get is the best.
What a refreshing team to have as competent suppliers for our leads and compressed air; not once have they given us poor service. They've saved our business; A Gilligan (Coatings) Ltd thousands of pounds per year with new high tech and efficient equipment. Their advice and service supplied over the last 15 year period has been extremely valuable, we would never consider another company for our compressed air services
Had a new compressor fitted a few months ago. Perfect service and amazing aftercare. I was advised well and even advised towards a better value option saving us a chunk of money. Top quality honest service all round...... Thanks again.
